Didn’t try that: After several days of always the same failure, `guix
pull` is suddenly working again. So if this comes down to a networking
issue, I wonder what went wrong for several days that did not affect
any other service.

This is a bit embarrasing: I have been using `guix package
--delete-generations; guix gc --collect-garbage` frequently and up to
this day did not realize that there’s another “level”, which can be
dealt with via `guix gc --delete-generations`.

Many thanks for your help, simon!
