• About

  GNU Guix is a transactional package manager and an advanced
  distribution of the GNU system that respects user freedom.  Guix can
  be used on top of any system running the Hurd or the Linux kernel, or
  it can be used as a standalone operating system distribution for i686,
  x86_64, ARMv7, AArch64 and POWER9 machines.

  In addition to standard package management features, Guix supports
  transactional upgrades and roll-backs, unprivileged package
  management, per-user profiles, and garbage collection.  When used as a
  standalone GNU/Linux distribution, Guix offers a declarative,
  stateless approach to operating system configuration management.  Guix
  is highly customizable and hackable through Guile programming
  interfaces and extensions to the Scheme language.

  .sig suffix) is intact.  First, be sure to download both the .sig file
  and the corresponding tarball.  Then, run a command like this:

    gpg --verify guix-1.3.0.tar.gz.sig

  If that command fails because you don't have the required public key,
  then run this command to import it:

    gpg --keyserver keys.gnupg.net --recv-keys

  and rerun the 'gpg --verify' command.
