Re: Trying to replicate guix packages list on another machine

It's possible your packages on machine A are from various guix revisions, if you didn't run "guix update" or didn't use a manifest to install them.

Yes you are right, that is certainly the case

Eg you run "guix install glibc" at revision A, pull revision B where glibc was updated to 2.34. When you list your packages, it still mentions glibc@2.33 because you didn't update it. Then you try to replicate it on another machine by pulling revision B, but that old glibc is no longer available.

Manifests ensure that all packages are from the same revision, although if you pull a new guix without reinstalling the manifest, you'll have the same issue because you're confusing the guix version from which the package was installed, and the current guix version.

Then how to install this previous glibc with other packages on machine B ?

    Hello,

    We are trying to replicate guix packages list on another machine. We are 
using GUIX on a foreign distro.

    Here what we have on machine A:

    [Machine A]$ guix describe --format=channels
    (list (channel
             (name 'guix)
             (url"https://git.savannah.gnu.org/git/guix.git";)
             (commit
               "a0178d34f582b50e9bdbb0403943129ae5b560ff")
             (introduction
               (make-channel-introduction
                 "9edb3f66fd807b096b48283debdcddccfea34bad"
                 (openpgp-fingerprint
                   "BBB0 2DDF 2CEA F6A8 0D1D  E643 A2A0 6DF2 A33A 54FA")))))

    [Machine A]$ guix package --list-installed  | sort | awk '//{ print $1 "@" 
$2; }'
    cmake@3.19.2
    gcc-toolchain@4.9.4
    glibc@2.33
    gsl@2.6
    icu4c@68.2
    make@4.3
    pcre@8.44
    zlib@1.2.11

    But on machine B:

    [Machine B]$ cat ~/.config/guix/channels.scm
    (list (channel
             (name 'guix)
             (url"https://git.savannah.gnu.org/git/guix.git";)
             (commit
               "a0178d34f582b50e9bdbb0403943129ae5b560ff")
             (introduction
               (make-channel-introduction
                 "9edb3f66fd807b096b48283debdcddccfea34bad"
                 (openpgp-fingerprint
                   "BBB0 2DDF 2CEA F6A8 0D1D  E643 A2A0 6DF2 A33A 54FA")))))

    [Machine B]$ guix installcmake@3.19.2  gcc-toolchain@4.9.4  glibc@2.33  
gsl@2.6  icu4c@68.2  make@4.3  pcre@8.44  zlib@1.2.11
    guix install: error: glibc: package not found for version 2.33

    What are we doing wrong ? Please tell us what steps are missing to 
correctly replicate guix packages to another machine ?

    Best regards,
