Probably network problems, just retry, and maybe pass --fallback to
"guix pull".

Anyway, this is not a bug and hence shouldn't be reported as such, but
error reporting in "guix pull" is complicated™.  FWIW, the v2 patch at
<https://issues.guix.gnu.org/50238> would avoid the here unnecessary
backtrace and make it clearer that it's just some network problems,
though it's not perfect (the ‘please report a bug’ remains).

Greetings,
Maxime.
