 DNF Configuration Reference

#############################

=============

 Description

=============

`DNF`_ by default uses the global configuration file at ``/etc/dnf/dnf.conf`` and

all \*.repo files found under ``/etc/yum.repos.d``. The latter is typically used

for repository configuration and takes precedence over global configuration.

The configuration file has INI format consisting of section declaration and

``name=value`` options below each on separate line. There are two types of sections

in the configuration files: main and repository. Main section defines all global

configuration options and should be only one.

The repository sections define the configuration for each (remote or local)

repository. The section name of the repository in brackets serve as repo ID reference

and should be unique across configuration files. The allowed characters of repo ID

string are lower and upper case alphabetic letters, digits, ``-``, ``_``, ``.``

and ``:``. The minimal repository configuration file should aside from repo ID

consists of :ref:`baseurl <baseurl-label>`, :ref:`metalink <metalink-label>`

or :ref:`mirrorlist <mirrorlist-label>` option definition.

.. _conf_distribution_specific-label:

=====================================

 Distribution-Specific Configuration

=====================================

Configuration options, namely :ref:`best <best-label>` and

:ref:`skip_if_unavailable <skip_if_unavailable-label>`, can be set in the DNF

configuration file by your distribution to override the DNF defaults.

.. _conf_main_options-label:

================

 [main] Options

================

.. _arch-label:

``arch``

    :ref:`string <string-label>`

    The architecture used for installing packages. By default this is auto-detected. Often used

    together with :ref:`ignorearch <ignorearch-label>` option.

.. _assumeno-label:

``assumeno``

    :ref:`boolean <boolean-label>`

    If enabled dnf will assume ``No`` where it would normally prompt for

    confirmation from user input. Default is ``False``.

.. _assumeyes-label:

``assumeyes``

    :ref:`boolean <boolean-label>`

    If enabled dnf will assume ``Yes`` where it would normally prompt for

    confirmation from user input (see also :ref:`defaultyes <defaultyes-label>`). Default is ``False``.

.. _autocheck_running_kernel-label:

``autocheck_running_kernel``

    :ref:`boolean <boolean-label>`

    Automatic check whether there is installed newer kernel module with security update than currently running kernel. Default is ``True``.

``basearch``

    :ref:`string <string-label>`

    The base architecture used for installing packages. By default this is auto-detected.

.. _best-label:

``best``

    :ref:`boolean <boolean-label>`

    ``True`` instructs the solver to either use a package with the highest available

    version or fail. On ``False``, do not fail if the latest version cannot be

    installed and go with the lower version. The default is ``True``.  Note

    this option in particular :ref:`can be set in your configuration file by

    your distribution <conf_distribution_specific-label>`.

``cachedir``

    :ref:`string <string-label>`

    Path to a directory used by various DNF subsystems for storing cache data.

    Has a reasonable root-writable default depending on the distribution. DNF

    needs to be able to create files and directories at this location.

``cacheonly``

    :ref:`boolean <boolean-label>`

    If set to ``True`` DNF will run entirely from system cache, will not update

    the cache and will use it even in case it is expired. Default is ``False``.

.. _check_config_file_age-label:

``check_config_file_age``

    :ref:`boolean <boolean-label>`

    Specifies whether dnf should automatically expire metadata of repos, which are older than

    their corresponding configuration file (usually the dnf.conf file and the foo.repo file).

    Default is ``True`` (perform the check). Expire of metadata is also affected by metadata age.

    See also :ref:`metadata_expire <metadata_expire-label>`.

.. _clean_requirements_on_remove-label:

``clean_requirements_on_remove``

    :ref:`boolean <boolean-label>`

    Remove dependencies that are no longer used during ``dnf remove``. A package

    only qualifies for removal via ``clean_requirements_on_remove`` if it was

    installed through DNF but not on explicit user request, i.e. it was

    pulled in as a dependency. The default is True.

    (:ref:`installonlypkgs <installonlypkgs-label>` are never automatically removed.)

``config_file_path``

    :ref:`string <string-label>`

    Path to the default main configuration file. Default is ``/etc/dnf/dnf.conf``.

``debuglevel``

    :ref:`integer <integer-label>`

    Debug messages output level, in the range 0 to 10. The higher the number the

    more debug output is put to stdout. Default is 2.

``debug_solver``

    :ref:`boolean <boolean-label>`

    Controls whether the libsolv debug files should be created when solving the

    transaction. The debug files are created in the `./debugdata` directory.

    Default is ``False``.

.. _defaultyes-label:

``defaultyes``

    :ref:`boolean <boolean-label>`

    If enabled the default answer to user confirmation prompts will be ``Yes``. Not

    to be confused with :ref:`assumeyes <assumeyes-label>` which will not prompt at all. Default is ``False``.

``diskspacecheck``

    :ref:`boolean <boolean-label>`

    Controls wheather rpm shoud check available disk space during the transaction.

    Default is ``True``.

``errorlevel``

    :ref:`integer <integer-label>`

    Error messages output level, in the range 0 to 10. The higher the number the

    more error output is put to stderr. Default is 3. This is deprecated in DNF

    and overwritten by \-\ :ref:`-verbose <verbose_options-label>` commandline

    option.

``exit_on_lock``

    :ref:`boolean <boolean-label>`

    Should the dnf client exit immediately when something else has the lock. Default is ``False``.

``gpgkey_dns_verification``

    :ref:`boolean <boolean-label>`

    Should the dnf attempt to automatically verify GPG verification keys using the DNS

    system. This option requires libunbound to be installed on the client system. This

    system has two main features. The first one is to check if any of the already

    installed keys have been revoked. Automatic removal of the key is not yet available,

    so it is up to the user, to remove revoked keys from the system. The second feature is

    automatic verification of new keys when a repository is added to the system. In

    interactive mode, the result is written to the output as a suggestion to the user. In

    non-interactive mode (i.e. when -y is used), this system will automatically accept

    keys that are available in the DNS and are correctly signed using DNSSEC. It will also

    accept keys that do not exist in the DNS system and their NON-existence is

    cryptographically proven using DNSSEC. This is mainly to preserve backward

    compatibility.

    Default is ``False``.

``group_package_types``

    :ref:`list <list-label>`

    List of the following: optional, default, mandatory. Tells dnf which type of packages in groups will

    be installed when 'groupinstall' is called. Default is: ``default, mandatory``.

.. _ignorearch-label:

``ignorearch``

    :ref:`boolean <boolean-label>`

    If set to ``True``, RPM will allow attempts to install packages incompatible with the CPU's

    architecture. Defaults to ``False``. Often used together with

    :ref:`arch <arch-label>` option.

.. _installonlypkgs-label:

``installonlypkgs``

    :ref:`list <list-label>`

    List of provide names of packages that should only ever be installed, never

    upgraded. Kernels in particular fall into this category.

    These packages are never removed by ``dnf autoremove`` even if they were

    installed as dependencies (see

    :ref:`clean_requirements_on_remove <clean_requirements_on_remove-label>`

    for auto removal details).

    This option append the list values to the default installonlypkgs list used

    by DNF. The number of kept package versions is regulated

    by :ref:`installonly_limit <installonly-limit-label>`.

.. _installonly-limit-label:

``installonly_limit``

    :ref:`integer <integer-label>`

    Number of :ref:`installonly packages <installonlypkgs-label>` allowed to be installed

    concurrently. Defaults to 3. The minimal number of installonly packages is 2. Value 0 or 1 means

    unlimited number of installonly packages.

``installroot``

    :ref:`string <string-label>`

    The root of the filesystem for all packaging operations. It requires an absolute path. See also :ref:`--installroot commandline option <installroot-label>`.

``install_weak_deps``

    :ref:`boolean <boolean-label>`

    When this option is set to True and a new package is about to be

    installed, all packages linked by weak dependency relation (Recommends or Supplements flags) with this package will be pulled into the transaction.

    Default is ``True``.

.. _keepcache-label:

``keepcache``

    :ref:`boolean <boolean-label>`

    Keeps downloaded packages in the cache when set to True. Even if it is set to False and packages have not been

    installed they will still persist until next successful transaction. The default

    is ``False``.

``logdir``

    :ref:`string <string-label>`

    Directory where the log files will be stored. Default is ``/var/log``.

.. _log_rotate-label:

``log_rotate``

    :ref:`integer <integer-label>`

    Log files are rotated ``log_rotate`` times before being removed. If ``log_rotate``

    is ``0``, the rotation is not performed.

    Default is ``4``.

.. _log_size-label:

``log_size``

    storage size

    Log  files are rotated when they grow bigger than log_size bytes. If

    log_size is 0, the rotation is not performed. The default is 1 MB. Valid

    units are 'k', 'M', 'G'.

    The size applies for individual log files, not the sum of all log files.

    See also :ref:`log_rotate <log_rotate-label>`.

.. _metadata_timer_sync-label:

``metadata_timer_sync``

    time in seconds

    The minimal period between two consecutive ``makecache timer`` runs. The

    command will stop immediately if it's less than this time period since its

    last run. Does not affect simple ``makecache`` run. Use ``0`` to completely

    disable automatic metadata synchronizing. The default corresponds to three

    hours. The value is rounded to the next commenced hour.

.. _module_platform_id-label:

``module_platform_id``

    :ref:`string <string-label>`

    Set this to $name:$stream to override PLATFORM_ID detected from ``/etc/os-release``.

    It is necessary to perform a system upgrade and switch to a new platform.

``multilib_policy``

    :ref:`string <string-label>`

    Controls how multilib packages are treated during install operations. Can either be ``"best"`` (the default) for the depsolver to prefer packages which best match the system's architecture, or ``"all"`` to install all available packages with compatible architectures.

.. _obsoletes_conf_option-label:

``obsoletes``

    :ref:`boolean <boolean-label>`

    This option only has affect during an install/update. It enables

    dnf's obsoletes processing logic, which means it makes dnf check whether

    any dependencies of given package are no longer required and removes them.

    Useful when doing distribution level upgrades.

    Default is 'true'.

    Command-line option: :ref:`--obsoletes <obsoletes_option-label>`

``persistdir``

    :ref:`string <string-label>`

    Directory where DNF stores its persistent data between runs. Default is ``"/var/lib/dnf"``.

``pluginconfpath``

    :ref:`list <list-label>`

    List of directories that are searched for plugin configurations to load. All

    configuration files found in these directories, that are named same as a

    plugin, are parsed. The default path is ``/etc/dnf/plugins``.

.. _pluginpath-label:

``pluginpath``

    :ref:`list <list-label>`

    List of directories that are searched for plugins to load. Plugins found in *any of the directories* in this configuration option are used. The default contains a Python version-specific path.

``plugins``

    :ref:`boolean <boolean-label>`

    Controls whether the plugins are enabled. Default is ``True``.

``protected_packages``

    :ref:`list <list-label>`

    List of packages that DNF should never completely remove. They are protected via Obsoletes as well as user/plugin removals.

    The default is: ``dnf``, ``glob:/etc/yum/protected.d/*.conf`` and ``glob:/etc/dnf/protected.d/*.conf``. So any packages which should be protected can do so by including a file in ``/etc/dnf/protected.d`` with their package name in it.

    DNF will protect also the package corresponding to the running version of the kernel.

``releasever``

    :ref:`string <string-label>`

    Used for substitution of ``$releasever`` in the repository configuration.

    See also :ref:`repo variables <repo-variables-label>`.

.. _reposdir-label:

``reposdir``

    :ref:`list <list-label>`

    DNF searches for repository configuration files in the paths specified by

    ``reposdir``. The behavior of ``reposdir`` could differ when it is used

    along with \-\ :ref:`-installroot <installroot-label>` option.

``rpmverbosity``

    :ref:`string <string-label>`

    RPM debug scriptlet output level. One of: ``critical``, ``emergency``,

    ``error``, ``warn``, ``info`` or ``debug``. Default is ``info``.

.. _strict-label:

``strict``

    :ref:`boolean <boolean-label>`

    If disabled, all unavailable packages or packages with broken dependencies given to DNF command will be skipped without raising the error causing the whole operation to fail. Currently works for install command only. The default is True.

``tsflags``

    :ref:`list <list-label>`

    List of strings adding extra flags for the RPM transaction.

    ============  ===========================

    tsflag value  RPM Transaction Flag

    ============  ===========================

    noscripts     RPMTRANS_FLAG_NOSCRIPTS

    test          RPMTRANS_FLAG_TEST

    notriggers    RPMTRANS_FLAG_NOTRIGGERS

    nodocs        RPMTRANS_FLAG_NODOCS

    justdb        RPMTRANS_FLAG_JUSTDB

    nocontexts    RPMTRANS_FLAG_NOCONTEXTS

    nocaps        RPMTRANS_FLAG_NOCAPS

    nocrypto      RPMTRANS_FLAG_NOFILEDIGEST

    ============  ===========================

    The ``nocrypto`` option will also set the ``_RPMVSF_NOSIGNATURES`` and

    ``_RPMVSF_NODIGESTS`` VS flags. The ``test`` option provides a transaction check

    without performing the transaction. It includes downloading of packages, gpg keys check

    (including permanent import of additional keys if necessary), and rpm check to prevent

    file conflicts.

    The ``nocaps`` is supported with rpm-4.14 or later. When ``nocaps`` is used but rpm

    doesn't support it, DNF only reports it as an invalid tsflag.

``upgrade_group_objects_upgrade``

    :ref:`boolean <boolean-label>`

    Set this to False to disable the automatic running of ``group upgrade`` when running the ``upgrade`` command. Default is ``True`` (perform the operation).

.. _varsdir_options-label:

``varsdir``

    :ref:`list <list-label>`

    List of directories where variables definition files are looked for. Defaults to

    ``"/etc/dnf/vars", "/etc/yum/vars"``. See :ref:`variable files <varfiles-label>`

    in Configuration reference.

.. _conf_repo_options-label:

``zchunk``

    :ref:`boolean <boolean-label>`

    Enables or disables the use of repository metadata compressed using the zchunk format (if available). Default is ``True``.

==============

 Repo Options

==============

.. _baseurl-label:

``baseurl``

    :ref:`list <list-label>`

    List of URLs for the repository. Defaults to ``[]``.

.. _repo_cost-label:

``cost``

    :ref:`integer <integer-label>`

    The relative cost of accessing this repository, defaulting to 1000. This

    value is compared when the priorities of two repositories are the same. The

    repository with *the lowest cost* is picked. It is useful to make the

    library prefer on-disk repositories to remote ones.

``enabled``

    :ref:`boolean <boolean-label>`

    Include this repository as a package source. The default is True.

.. _repo_gpgkey-label:

``gpgkey``

    :ref:`list <list-label>` of strings

    URLs of a GPG key files that can be used for signing metadata and packages of this repository, empty by default. If a file can not be verified using the already imported keys, import of keys from this option is attempted and the keys are then used for verification.

.. _metalink-label:

``metalink``

    :ref:`string <string-label>`

    URL of a metalink for the repository. Defaults to ``None``.

.. _mirrorlist-label:

``mirrorlist``

    :ref:`string <string-label>`

    URL of a mirrorlist for the repository. Defaults to ``None``.

.. _module_hotfixes-label:

``module_hotfixes``

    :ref:`boolean <boolean-label>`

    Set this to True to disable module RPM filtering and make all RPMs from the repository available. The default is False.

    This allows user to create a repository with cherry-picked hotfixes that are included in a package set on a modular system.

.. _repo_name-label:

``name``

    :ref:`string <string-label>`

    A human-readable name of the repository. Defaults to the ID of the repository.

.. _repo_priority-label:

``priority``

    :ref:`integer <integer-label>`

    The priority value of this repository, default is 99. If there is more than one candidate package for a particular operation, the one from a repo with *the lowest priority value* is picked, possibly despite being less convenient otherwise (e.g. by being a lower version).

``type``

    :ref:`string <string-label>`

    Type of repository metadata. Supported values are: ``rpm-md``.

    Aliases for ``rpm-md``: ``rpm``, ``repomd``, ``rpmmd``, ``yum``, ``YUM``.

.. _repo-variables-label:

================

 Repo Variables

================

Right side of every repo option can be enriched by the following variables:

``$arch``

    Refers to the system’s CPU architecture e.g, aarch64, i586, i686 and x86_64.

``$basearch``

    Refers to the base architecture of the system. For example, i686 and i586 machines

    both have a base architecture of i386, and AMD64 and Intel64 machines have a base architecture of x86_64.

``$releasever``

    Refers to the release version of operating system which DNF derives from information available in RPMDB.

In addition to these hard coded variables, user-defined ones can also be used. They can be defined either via :ref:`variable files <varfiles-label>`, or by using special environmental variables. The names of these variables must be prefixed with DNF_VAR\_ and they can only consist of alphanumeric characters and underscores::

    $ DNF_VAR_MY_VARIABLE=value

.. _conf_main_and_repo_options-label:

==================================

 Options for both [main] and Repo

==================================

Some options can be applied in either the main section, per repository, or in a

combination. The value provided in the main section is used for all repositories

as the default value, which repositories can then override in their

configuration.

.. _bandwidth-label:

``bandwidth``

    storage size

    Total bandwidth available for downloading. Meaningful when used with the :ref:`throttle option <throttle-label>`. Storage size is in bytes by default but can be specified with a unit of storage. Valid units are 'k', 'M', 'G'.

``countme``

    :ref:`boolean <boolean-label>`

    Determines whether a special flag should be added to a single, randomly

    chosen metalink/mirrorlist query each week.

    This allows the repository owner to estimate the number of systems

    consuming it, by counting such queries over a week's time, which is much

    more accurate than just counting unique IP addresses (which is subject to

    both overcounting and undercounting due to short DHCP leases and NAT,

    respectively).

    The flag is a simple "countme=N" parameter appended to the metalink and

    mirrorlist URL, where N is an integer representing the "longevity" bucket

    this system belongs to.

    The following 4 buckets are defined, based on how many full weeks have

    passed since the beginning of the week when this system was installed: 1 =

    first week, 2 = first month (2-4 weeks), 3 = six months (5-24 weeks) and 4

    = more than six months (> 24 weeks).

    This information is meant to help distinguish short-lived installs from

    long-term ones, and to gather other statistics about system lifecycle.

    Default is False.

.. _deltarpm-label:

``deltarpm``

    :ref:`boolean <boolean-label>`

    When enabled, DNF will save bandwidth by downloading much smaller delta RPM

    files, rebuilding them to RPM locally. However, this is quite CPU and I/O

    intensive. Default is True.

``deltarpm_percentage``

    :ref:`integer <integer-label>`

    When the relative size of delta vs pkg is larger than this, delta is not used.  Default value is 75

    (Deltas must be at least 25% smaller than the pkg).  Use `0` to turn off delta rpm processing. Local repositories (with

    file:// baseurl) have delta rpms turned off by default.

``enablegroups``

    :ref:`boolean <boolean-label>`

    Determines whether DNF will allow the use of package groups for this repository. Default is True (package groups are allowed).

.. _exclude-label:

``excludepkgs``

    :ref:`list <list-label>`

    Exclude packages of this repository, specified by a name or a glob and

    separated by a comma, from all operations.

    Can be disabled using ``--disableexcludes`` command line switch.

    Defaults to ``[]``.

``fastestmirror``

    :ref:`boolean <boolean-label>`

    If enabled a metric is used to find the fastest available mirror. This overrides the order provided by the mirrorlist/metalink file itself. This file is often dynamically generated by the server to provide the best download speeds and enabling fastestmirror overrides this. The default is False.

.. _gpgcheck-label:

``gpgcheck``

    :ref:`boolean <boolean-label>`

    Whether to perform GPG signature check on packages found in this repository.

    The default is False.

    This option can only be used to strengthen the active RPM security policy set with the ``%_pkgverify_level`` macro (see the ``/usr/lib/rpm/macros`` file for details).

    That means, if the macro is set to 'signature' or 'all' and this option is False, it will be overridden to True during DNF runtime, and a warning will be printed.

    To squelch the warning, make sure this option is True for every enabled repository, and also enable :ref:`localpkg_gpgcheck <localpkg_gpgcheck-label>`.

.. _include-label:

``includepkgs``

    :ref:`list <list-label>`

    Include packages of this repository, specified by a name or a glob and separated by a comma, in all operations.

    Inverse of :ref:`excludepkgs <exclude-label>`, DNF will exclude any package in the repository that doesn't match this list. This works in conjunction with exclude and doesn't override it, so if you 'excludepkgs=*.i386' and 'includepkgs=python*' then only packages starting with python that do not have an i386 arch will be seen by DNF in this repo.

    Can be disabled using ``--disableexcludes`` command line switch.

    Defaults to ``[]``.

.. _ip-resolve-label:

``ip_resolve``

    IP address type

    Determines how DNF resolves host names. Set this to '4'/'IPv4' or '6'/'IPv6' to resolve to IPv4 or IPv6 addresses only. By default, DNF resolves to either addresses.

.. _localpkg_gpgcheck-label:

``localpkg_gpgcheck``

    :ref:`boolean <boolean-label>`

    Whether to perform a GPG signature check on local packages (packages in a file, not in a repository).

    The default is False.

    This option is subject to the active RPM security policy (see :ref:`gpgcheck <gpgcheck-label>` for more details).

``max_parallel_downloads``

    :ref:`integer <integer-label>`

    Maximum number of simultaneous package downloads. Defaults to 3.

.. _metadata_expire-label:

``metadata_expire``

    time in seconds

    The period after which the remote repository is checked for metadata update and in the positive

    case the local metadata cache is updated. The default corresponds to 48 hours. Set this to

    ``-1`` or ``never`` to make the repo never considered expired. Expire of metadata can bee also

    triggered by change of timestamp of configuration files (``dnf.conf``, ``<repo>.repo``). See

    also :ref:`check_config_file_age <check_config_file_age-label>`.

.. _minrate-label:

``minrate``

    storage size

    This sets the low speed threshold in bytes per second. If the server is sending data at the same or slower speed than this value for at least :ref:`timeout option <timeout-label>` seconds, DNF aborts the connection. The default is 1000. Valid units are 'k', 'M', 'G'.

``password``

    :ref:`string <string-label>`

    The password to use for connecting to a repository with basic HTTP authentication. Empty by default.

``proxy``

    :ref:`string <string-label>`

    URL of a proxy server to connect through. Set to an empty string to disable the proxy setting inherited from the main section and use direct connection instead. The expected format of this option is ``<scheme>://<ip-or-hostname>[:port]``.

    (For backward compatibility, '_none_' can be used instead of the empty string.)

    Note: The curl environment variables (such as ``http_proxy``) are effective if this option is unset. See the ``curl`` man page for details.

``proxy_username``

    :ref:`string <string-label>`

    The username to use for connecting to the proxy server. Empty by default.

``proxy_password``

    :ref:`string <string-label>`

    The password to use for connecting to the proxy server. Empty by default.

``proxy_auth_method``

    :ref:`string <string-label>`

    The authentication method used by the proxy server. Valid values are

    ==========     ==========================================================

    method         meaning

    ==========     ==========================================================

    basic          HTTP Basic authentication

    digest         HTTP Digest authentication

    negotiate      HTTP Negotiate (SPNEGO) authentication

    ntlm           HTTP NTLM authentication

    digest_ie      HTTP Digest authentication with an IE flavor

    ntlm_wb        NTLM delegating to winbind helper

    none           None auth method

    any            All suitable methods

    ==========     ==========================================================

    for any reason. This option doesn't affect skipping of unavailable packages after dependency

    resolution. To check inaccessibility of repository use it in combination with

    :ref:`refresh command line option <refresh_command-label>`. The default is ``False``.

    Note this option in particular :ref:`can be set in your configuration file

    by your distribution <conf_distribution_specific-label>`.

    storage size

    Limits the downloading speed. It might be an absolute value or a percentage, relative to the value of the :ref:`bandwidth option <bandwidth-label>` option. ``0`` means no throttling (the default). The absolute value is in bytes by default but can be specified with a unit of storage. Valid units are 'k', 'M', 'G'.

    :ref:`string <string-label>`

    The User-Agent string to include in HTTP requests sent by DNF.

    Defaults to ::

        libdnf (NAME VERSION_ID; VARIANT_ID; OS.BASEARCH)

    where NAME, VERSION_ID and VARIANT_ID are OS identifiers read from the

    :manpage:`os-release(5)` file, and OS and BASEARCH are the canonical OS

    name and base architecture, respectively.

    Example: ::

        libdnf (Fedora 31; server; Linux.x86_64)

    To avoid leaking identifiable data, the variant in the above string will be

    replaced by "generic" if the value is not an official Fedora variant.

    Likewise, the whole OS part (enclosed in parenthesis) will be omitted if

    this is a non-Fedora system.
