Ubuntu Manpage: pacman.conf - pacman package manager configuration file

Provided by: pacman-package-manager_6.0.2-6ubuntu2_amd64

NAME

       pacman.conf - pacman package manager configuration file

SYNOPSIS

       /etc/pacman.conf

DESCRIPTION

       Pacman, using libalpm(3), will attempt to read pacman.conf each time it is invoked. This configuration
       file is divided into sections or repositories. Each section defines a package repository that pacman can
       use when searching for packages in --sync mode. The exception to this is the options section, which
       defines global options.

       Comments are only supported by beginning a line with the hash (#) symbol. Comments cannot begin in the
       middle of a line.

EXAMPLE

           #
           # pacman.conf
           #
           [options]
           NoUpgrade = etc/passwd etc/group etc/shadow
           NoUpgrade = etc/fstab

           [core]
           Include = /etc/pacman.d/core

           [custom]
           Server = file:///home/pkgs

           Note

           Each directive must be in CamelCase. If the case isn’t respected, the directive won’t be recognized.
           For example. noupgrade or NOUPGRADE will not work.

OPTIONS

       RootDir = /path/to/root/dir
           Set the default root directory for pacman to install to. This option is used if you want to install a
           package on a temporary mounted partition which is "owned" by another system, or for a chroot install.
           NOTE: If database path or log file are not specified on either the command line or in pacman.conf(5),
           their default location will be inside this root path.

       DBPath = /path/to/db/dir
           Overrides the default location of the toplevel database directory. The default is /var/lib/pacman/.
           Most users will not need to set this option.  NOTE: if specified, this is an absolute path and the
           root path is not automatically prepended.

       CacheDir = /path/to/cache/dir
           Overrides the default location of the package cache directory. The default is /var/cache/pacman/pkg/.
           Multiple cache directories can be specified, and they are tried in the order they are listed in the
           config file. If a file is not found in any cache directory, it will be downloaded to the first cache
           directory with write access.  NOTE: this is an absolute path, the root path is not automatically
           prepended.

       HookDir = /path/to/hook/dir
           Add directories to search for alpm hooks in addition to the system hook directory
           (/usr/share/libalpm/hooks/). The default is /etc/pacman.d/hooks. Multiple directories can be
           specified with hooks in later directories taking precedence over hooks in earlier directories.  NOTE:
           this is an absolute path, the root path is not automatically prepended. For more information on the
           alpm hooks, see alpm-hooks(5).

       GPGDir = /path/to/gpg/dir
           Overrides the default location of the directory containing configuration files for GnuPG. The default
           is /etc/pacman.d/gnupg/. This directory should contain two files: pubring.gpg and trustdb.gpg.
           pubring.gpg holds the public keys of all packagers.  trustdb.gpg contains a so-called trust database,
           which specifies that the keys are authentic and trusted.  NOTE: this is an absolute path, the root
           path is not automatically prepended.

       LogFile = /path/to/log/file
           Overrides the default location of the pacman log file. The default is /var/log/pacman.log. This is an
           absolute path and the root directory is not prepended.

       HoldPkg = package ...
           If a user tries to --remove a package that’s listed in HoldPkg, pacman will ask for confirmation
           before proceeding. Shell-style glob patterns are allowed.

       IgnorePkg = package ...
           Instructs pacman to ignore any upgrades for this package when performing a --sysupgrade. Shell-style
           glob patterns are allowed.

       IgnoreGroup = group ...
           Instructs pacman to ignore any upgrades for all packages in this group when performing a
           --sysupgrade. Shell-style glob patterns are allowed.

       Include = /path/to/config/file
           Include another configuration file. This file can include repositories or general configuration
           options. Wildcards in the specified paths will get expanded based on glob(7) rules.

       Architecture = auto &| i686 &| x86_64 | ...
           If set, pacman will only allow installation of packages with the given architectures (e.g.  i686,
           x86_64, etc). The special value auto will use the system architecture, provided via “uname -m”. If
           unset, no architecture checks are made.  NOTE: Packages with the special architecture any can always
           be installed, as they are meant to be architecture independent.

       XferCommand = /path/to/command %u
           If set, an external program will be used to download all remote files. All instances of %u will be
           replaced with the download URL. If present, instances of %o will be replaced with the local filename,
           plus a “.part” extension, which allows programs like wget to do file resumes properly.

           This option is useful for users who experience problems with built-in HTTP/FTP support, or need the
           more advanced proxy support that comes with utilities like wget.

       NoUpgrade = file ...
           All files listed with a NoUpgrade directive will never be touched during a package install/upgrade,
           and the new files will be installed with a .pacnew extension. These files refer to files in the
           package archive, so do not include the leading slash (the RootDir) when specifying them. Shell-style
           glob patterns are allowed. It is possible to invert matches by prepending a file with an exclamation
           mark. Inverted files will result in previously blacklisted files being whitelisted again. Subsequent
           matches will override previous ones. A leading literal exclamation mark or backslash needs to be
           escaped.

       NoExtract = file ...
           All files listed with a NoExtract directive will never be extracted from a package into the
           filesystem. This can be useful when you don’t want part of a package to be installed. For example, if
           your httpd root uses an index.php, then you would not want the index.html file to be extracted from
           the apache package. These files refer to files in the package archive, so do not include the leading
           slash (the RootDir) when specifying them. Shell-style glob patterns are allowed. It is possible to
           invert matches by prepending a file with an exclamation mark. Inverted files will result in
           previously blacklisted files being whitelisted again. Subsequent matches will override previous ones.
           A leading literal exclamation mark or backslash needs to be escaped.

       CleanMethod = KeepInstalled &| KeepCurrent
           If set to KeepInstalled (the default), the -Sc operation will clean packages that are no longer
           installed (not present in the local database). If set to KeepCurrent, -Sc will clean outdated
           packages (not present in any sync database). The second behavior is useful when the package cache is
           shared among multiple machines, where the local databases are usually different, but the sync
           databases in use could be the same. If both values are specified, packages are only cleaned if not
           installed locally and not present in any known sync database.

       SigLevel = ...
           Set the default signature verification level. For more information, see Package and Database
           Signature Checking below.

       LocalFileSigLevel = ...
           Set the signature verification level for installing packages using the "-U" operation on a local
           file. Uses the value from SigLevel as the default.

       RemoteFileSigLevel = ...
           Set the signature verification level for installing packages using the "-U" operation on a remote
           file URL. Uses the value from SigLevel as the default.

       UseSyslog
           Log action messages through syslog(). This will insert log entries into /var/log/messages or
           equivalent.

       Color
           Automatically enable colors only when pacman’s output is on a tty.

       NoProgressBar
           Disables progress bars. This is useful for terminals which do not support escape characters.

       CheckSpace
           Performs an approximate check for adequate available disk space before installing packages.

       VerbosePkgLists
           Displays name, version and size of target packages formatted as a table for upgrade, sync and remove
           operations.

       DisableDownloadTimeout
           Disable defaults for low speed limit and timeout on downloads. Use this if you have issues
           downloading files with proxy and/or security gateway.

       ParallelDownloads = ...
           Specifies number of concurrent download streams. The value needs to be a positive integer. If this
           config option is not set then only one download stream is used (i.e. downloads happen sequentially).

REPOSITORY SECTIONS

Each repository section defines a section name and at least one location where the packages can be found.
The section name is defined by the string within square brackets (the two above are core and custom).
Repository names must be unique and the name local is reserved for the database of installed packages.
Locations are defined with the Server directive and follow a URL naming structure. If you want to use a
local directory, you can specify the full path with a “file://” prefix, as shown above.

A common way to define DB locations utilizes the Include directive. For each repository defined in the
configuration file, a single Include directive can contain a file that lists the servers for that
repository.

[core]
# use this server first
Server = ftp://ftp.archlinux.org/$repo/os/$arch
# next use servers as defined in the mirrorlist below
Include = {sysconfdir}/pacman.d/mirrorlist

The order of repositories in the configuration files matters; repositories listed first will take
precedence over those listed later in the file when packages in two repositories have identical names,
regardless of version number.

Include = path
Include another config file. This file can include repositories or general configuration options.
Wildcards in the specified paths will get expanded based on glob(7) rules.

Server = url
A full URL to a location where the database, packages, and signatures (if available) for this
repository can be found.

During parsing, pacman will define the $repo variable to the name of the current section. This is
often utilized in files specified using the Include directive so all repositories can use the same
mirrorfile. pacman also defines the $arch variable to the first (or only) value of the Architecture
option, so the same mirrorfile can even be used for different architectures.

SigLevel = ...
Set the signature verification level for this repository. For more information, see Package and
Database Signature Checking below.

Usage = ...
Set the usage level for this repository. This option takes a list of tokens which must be at least
one of the following:

Sync
Enables refreshes for this repository.

Search
Enables searching for this repository.

Install
Enables installation of packages from this repository during a --sync operation.

Upgrade
Allows this repository to be a valid source of packages when performing a --sysupgrade.

All
Enables all of the above features for the repository. This is the default if not specified.

Note that an enabled repository can be operated on explicitly, regardless of the Usage level set.

PACKAGE AND DATABASE SIGNATURE CHECKING

The SigLevel directive is valid in both the [options] and repository sections. If used in [options], it
sets a default value for any repository that does not provide the setting.

• If set to Never, no signature checking will take place.

• If set to Optional , signatures will be checked when present, but unsigned databases and packages
will also be accepted.

• If set to Required, signatures will be required on all packages and databases.

Alternatively, you can get more fine-grained control by combining some of the options and prefixes
described below. All options in a config file are processed in top-to-bottom, left-to-right fashion,
where later options override and/or supplement earlier ones. If SigLevel is specified in a repository
section, the starting value is that from the [options] section, or the built-in system default as shown
below if not specified.

The options are split into two main groups, described below. Terms used such as “marginally trusted” are
terms used by GnuPG, for more information please consult gpg(1).

When to Check
These options control if and when signature checks should take place.

Never
All signature checking is suppressed, even if signatures are present.

Optional (default)
Signatures are checked if present; absence of a signature is not an error. An invalid signature
is a fatal error, as is a signature from a key not in the keyring.

Required
Signatures are required; absence of a signature or an invalid signature is a fatal error, as is a
signature from a key not in the keyring.

What is Allowed
These options control what signatures are viewed as permissible. Note that neither of these options
allows acceptance of invalid or expired signatures, or those from revoked keys.

TrustedOnly (default)
If a signature is checked, it must be in the keyring and fully trusted; marginal trust does not
meet this criteria.

TrustAll
If a signature is checked, it must be in the keyring, but is not required to be assigned a trust
level (e.g., unknown or marginal trust).

Options in both groups can additionally be prefixed with either Package or Database, which will cause it
to only take effect on the specified object type. For example, PackageTrustAll would allow marginal and
unknown trust level signatures for packages.

The built-in default is the following:

SigLevel = Optional TrustedOnly

USING YOUR OWN REPOSITORY

       If you have numerous custom packages of your own, it is often easier to generate your own custom local
       repository than install them all with the --upgrade option. All you need to do is generate a compressed
       package database in the directory with these packages so pacman can find it when run with --refresh.

           repo-add /home/pkgs/custom.db.tar.gz /home/pkgs/*.pkg.tar.gz

       The above command will generate a compressed database named /home/pkgs/custom.db.tar.gz. Note that the
       database must be of the form defined in the configuration file and {ext} is a valid compression type as
       documented in repo-add(8). That’s it! Now configure your custom section in the configuration file as
       shown in the config example above. Pacman will now use your package repository. If you add new packages
       to the repository, remember to re-generate the database and use pacman’s --refresh option.

       For more information on the repo-add command, see “repo-add --help” or repo-add(8).

BUGS

       Bugs? You must be kidding; there are no bugs in this software. But if we happen to be wrong, submit a bug
       report with as much detail as possible at the Arch Linux Bug Tracker in the Pacman section.
