Guix re-installing already installed packages

Guix re-installing already installed packages

[Tirifto]

Hello!

I installed TeXmacs using Guix on Parabola GNU+Linux-libre. TeXmacs is
already the newest version (1.99.11) and whenever I run ‘guix pull’, no
upgrades for TeXmacs are reported—so far, so good.

However, once I actually run ‘guix upgrade’, Guix starts downloading
TeXmacs with all of its dependencies again, even though it's already
up-to-date on my computer. Should this be happening?

I don't know if it's related, but ‘guix weather’ shows that there are
no substitutes available for TeXmacs.

Best wishes

With Guix, a package can be modified by a lot of parameters (inputs), not only
version. If you want to know if Guix is downloading the exact same
package, you should check its hash (which is the result of all its
inputs).
What probably happens here is that a dependency of Texmacs has changed
since your last guix pull which gives us a new version of Texmacs'
package.

Most of the time, just waiting should be enough to get the substitutes
but looking at ci.guix.info, it seems a dependency is failing on master
(but it's repaired on core-updates which should be merge soonish). But
don't quote me on that, I'm not really used to this tool.
