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

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 [%o]

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.

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.

CacheServer = url

A full URL to a location where the packages, and signatures (if available) for
this repository can be found. Cache servers will be tried before any non-cache
servers, will not be removed from the server pool for 404 download errors, and
will not be used for database files.

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).
