Packages are installed or upgraded to the latest version available in
the distribution currently available on your local machine. To update
that distribution, along with the Guix tools, you must run
pull: the command downloads the latest Guix source code and package
descriptions, and deploys it. Source code is downloaded from a
Git repository, by default the official
GNU Guix repository, though this can be customized.
guix package will use packages and package
versions from this just-retrieved copy of Guix. Not only that, but all
the Guix commands and Scheme modules will also be taken from that latest
guix sub-commands added by the update also
Any user can update their Guix copy using
guix pull, and the
effect is limited to the user who run
guix pull. For
instance, when user
guix pull, this has no
effect on the version of Guix that user
alice sees, and vice
The result of running
guix pull is a profile available
under ~/.config/guix/current containing the latest Guix. Thus,
make sure to add it to the beginning of your search path so that you use
the latest version, and similarly for the Info manual
export PATH="$HOME/.config/guix/current/bin:$PATH" export INFOPATH="$HOME/.config/guix/current/share/info:$INFOPATH"
-l option lists past generations
guix pull, along with details about their provenance:
$ guix pull -l Generation 1 Jun 10 2018 00:18:18 guix 65956ad repository URL: https://git.savannah.gnu.org/git/guix.git branch: origin/master commit: 65956ad3526ba09e1f7a40722c96c6ef7c0936fe Generation 2 Jun 11 2018 11:02:49 guix e0cc7f6 repository URL: https://git.savannah.gnu.org/git/guix.git branch: origin/master commit: e0cc7f669bec22c37481dd03a7941c7d11a64f1d 2 new packages: keepalived, libnfnetlink 6 packages upgraded: email@example.com, firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, email@example.com, firstname.lastname@example.org Generation 3 Jun 13 2018 23:31:07 (current) guix 844cc1c repository URL: https://git.savannah.gnu.org/git/guix.git branch: origin/master commit: 844cc1c8f394f03b404c5bb3aee086922373490c 28 new packages: emacs-helm-ls-git, emacs-helm-mu, … 69 packages upgraded: email@example.com, firstname.lastname@example.org, …
guix describe, for other ways to
describe the current status of Guix.
~/.config/guix/current profile works like any other profile
guix package (see Invoking guix package). That
is, you can list generations, roll back to the previous
generation—i.e., the previous Guix—and so on:
$ guix package -p ~/.config/guix/current --roll-back switched from generation 3 to 2 $ guix package -p ~/.config/guix/current --delete-generations=1 deleting /var/guix/profiles/per-user/charlie/current-guix-1-link
guix pull command is usually invoked with no arguments,
but it supports the following options:
Download code for the
guix channel from the specified url, at the
given commit (a valid Git commit ID represented as a hexadecimal
string), or branch.
These options are provided for convenience, but you can also specify your configuration in the ~/.config/guix/channels.scm file or using the --channels option (see below).
Read the list of channels from file instead of ~/.config/guix/channels.scm. file must contain Scheme code that evaluates to a list of channel objects. See Channels, for more information.
Display the list of packages added or upgraded since the previous generation.
This is the same information as displayed upon
guix pull completion,
but without ellipses; it is also similar to the output of
-l for the last generation (see below).
List all the generations of ~/.config/guix/current or, if pattern
is provided, the subset of generations that match pattern.
The syntax of pattern is the same as with
--list-generations (see Invoking guix package).
See Invoking guix describe, for a way to display information about the current generation only.
Use profile instead of ~/.config/guix/current.
Show which channel commit(s) would be used and what would be built or substituted but do not actually do it.
Attempt to build for system—e.g.,
the system type of the build host.
Produce verbose output, writing build logs to the standard error output.
Use the bootstrap Guile to build the latest Guix. This option is only useful to Guix developers.
The channel mechanism allows you to instruct
guix pull which
repository and branch to pull from, as well as additional repositories
containing package modules that should be deployed. See Channels, for more
guix pull supports all the common build options
(see Common Build Options).
