The initial report by André is about: --8<---------------cut here---------------start------------->8--- $ guix pull Updating channel 'nonguix' from Git repository at 'https://gitlab.com/nonguix/nonguix'... guix pull: error: Git error: unexpected http status code: 503 --8<---------------cut here---------------end--------------->8--- So the situation is more likely: Guix from Savannah is reachable and guix-foo is not. For sure, we can discuss the case when Guix is unavailable. However, the 'guix channel is special; see all conditionals using ’guix-channel?’. Well, %default-guix-channel is somehow a corner use-case when the regular use-case seems about a failure of additional channels. Cheers, simon
