9 pacman.conf - pacman package manager configuration file
14 {sysconfdir}/pacman.conf
19 Pacman, using linkman:libalpm[3], will attempt to read pacman.conf each time it
20 is invoked. This configuration file is divided into sections or repositories.
21 Each section defines a package repository that pacman can use when searching
22 for packages in '\--sync' mode. The exception to this is the options section,
23 which defines global options.
34 NoUpgrade = etc/passwd etc/group etc/shadow
38 Include = {sysconfdir}/pacman.d/core
41 Server = file:///home/pkgs
44 NOTE: Each directive must be in CamelCase. If the case isn't respected, the
45 directive won't be recognized. For example. noupgrade or NOUPGRADE will not
50 *RootDir =* path/to/root::
51 Set the default root directory for pacman to install to. This option is
52 used if you want to install a package on a temporary mounted partition
53 which is "owned" by another system, or for a chroot install.
54 *NOTE*: If database path or logfile are not specified on either the
55 command line or in linkman:pacman.conf[5], their default location will
56 be inside this root path.
58 *DBPath =* path/to/db/dir::
59 Overrides the default location of the toplevel database directory. A
60 typical default is ``{localstatedir}/lib/pacman/''. Most users will not need to set
61 this option. *NOTE*: if specified, this is an absolute path and the root
62 path is not automatically prepended.
64 *CacheDir =* path/to/cache/dir::
65 Overrides the default location of the package cache directory. A typical
66 default is ``{localstatedir}/cache/pacman/pkg/''. Multiple cache directories can be
67 specified, and they are tried in the order they are listed in the config
68 file. If a file is not found in any cache directory, it will be downloaded
69 to the first cache directory with write access. *NOTE*: this is an absolute
70 path, the root path is not automatically prepended.
73 *LogFile =* '/path/to/file'::
74 Overrides the default location of the pacman log file. A typical default
75 is ``{localstatedir}/log/pacman.log''. This is an absolute path and the root directory
78 *HoldPkg =* package ...::
79 If a user tries to '\--remove' a package that's listed in `HoldPkg`,
80 pacman will ask for confirmation before proceeding.
82 *IgnorePkg =* package ...::
83 Instructs pacman to ignore any upgrades for this package when performing
86 *SyncFirst =* package ...::
87 Instructs pacman to check for newer version of these packages before any
88 sync operation. The user will have the choice to either cancel the current
89 operation and upgrade these packages first or go on with the current
90 operation. This option is typically used with the 'pacman' package.
91 *NOTE*: when a `SyncFirst` transaction takes place, no command line flags
92 (e.g. '\--force') are honored. If this is not ideal, disabling `SyncFirst`
93 and performing a manual sync of the involved packages may be required.
95 *IgnoreGroup =* group ...::
96 Instructs pacman to ignore any upgrades for all packages in this
97 group when performing a '\--sysupgrade'.
100 Include another config file. This file can include repositories or
101 general configuration options. Wildcards in the specified paths will get
102 expanded based on linkman:glob[7] rules.
104 *Architecture =* auto | i686 | x86_64 | ...::
105 If set, pacman will only allow installation of packages of the given
106 architecture (e.g. 'i686', 'x86_64', etc). The special value 'auto' will
107 use the system architecture, provided by in ``uname -m''. If unset, no
108 architecture checks are made. *NOTE*: packages with the special
109 architecture 'any' can always be installed, as they are meant to be
110 architecture independent.
112 *XferCommand =* /path/to/command %u::
113 If set, an external program will be used to download all remote files.
114 All instances of `%u` will be replaced with the download URL. If present,
115 instances of `%o` will be replaced with the local filename, plus a
116 ``.part'' extension, which allows programs like wget to do file resumes
119 This option is useful for users who experience problems with built-in
120 http/ftp support, or need the more advanced proxy support that comes with
123 *NoUpgrade =* file ...::
124 All files listed with a `NoUpgrade` directive will never be touched during
125 a package install/upgrade, and the new files will be installed with a
127 These files refer to files in the package archive, so do not include the
128 leading slash (the RootDir) when specifying them.
130 *NoExtract =* file ...::
131 All files listed with a `NoExtract` directive will never be extracted from
132 a package into the filesystem. This can be useful when you don't want part
133 of a package to be installed. For example, if your httpd root uses an
134 'index.php', then you would not want the 'index.html' file to be extracted
135 from the 'apache' package.
136 These files refer to files in the package archive, so do not include the
137 leading slash (the RootDir) when specifying them.
139 *CleanMethod =* KeepInstalled &| KeepCurrent::
140 If set to `KeepInstalled` (the default), the '-Sc' operation will clean
141 packages that are no longer installed (not present in the local database).
142 If set to `KeepCurrent`, '-Sc' will clean outdated packages (not present in
144 The second behavior is useful when the package cache is shared among
145 multiple machines, where the local databases are usually different, but the
146 sync databases in use could be the same. If both values are specified,
147 packages are only cleaned if not installed locally and not present in any
151 Log action messages through syslog(). This will insert log entries into
152 ``{localstatedir}/log/messages'' or equivalent.
155 Display the size of individual packages for '\--sync' and '\--query' modes.
158 Download delta files instead of complete packages if possible. Requires
159 the xdelta3 program to be installed.
162 When downloading, display the amount downloaded, download rate, ETA,
163 and completed percentage of the entire download list rather
164 than the percent of each individual download target. The progress
165 bar is still based solely on the current file download.
168 Performs an approximate check for adequate available disk space before
173 Each repository section defines a section name and at least one location where
174 the packages can be found. The section name is defined by the string within
175 square brackets (the two above are 'current' and 'custom'). Locations are
176 defined with the 'Server' directive and follow a URL naming structure. If you
177 want to use a local directory, you can specify the full path with a ``file://''
178 prefix, as shown above.
180 A common way to define DB locations utilizes the 'Include' directive. For each
181 repository defined in the configuration file, a single 'Include' directive can
182 contain a file that lists the servers for that repository.
186 # use this repository first
187 Server = ftp://ftp.archlinux.org/core/os/arch
188 # next use servers as defined in the mirrorlist below
189 Include = {sysconfdir}/pacman.d/mirrorlist
192 During parsing, pacman will define the `$repo` variable to the name of the
193 current section. This is often utilized in files specified using the 'Include'
194 directive so all repositories can use the same mirrorfile. pacman also defines
195 the `$arch` variable to the value of `Architecture`, so the same mirrorfile can
196 even be used for different architectures.
199 Server = ftp://ftp.archlinux.org/$repo/os/$arch
202 The order of repositories in the configuration files matters; repositories
203 listed first will take precedence over those listed later in the file when
204 packages in two repositories have identical names, regardless of version
207 Using Your Own Repository
208 -------------------------
209 If you have numerous custom packages of your own, it is often easier to generate
210 your own custom local repository than install them all with the '\--upgrade'
211 option. All you need to do is generate a compressed package database in the
212 directory with these packages so pacman can find it when run with '\--refresh'.
214 repo-add /home/pkgs/custom.db.tar.gz /home/pkgs/*.pkg.tar.gz
216 The above command will generate a compressed database named
217 '/home/pkgs/custom.db.tar.gz'. Note that the database must be of the form
218 '{treename}.db.tar.gz', where '{treename}' is the name of the section defined in
219 the configuration file. That's it! Now configure your custom section in the
220 configuration file as shown in the config example above. Pacman will now use your
221 package repository. If you add new packages to the repository, remember to
222 re-generate the database and use pacman's '\--refresh' option.
