See <https://debbugs.gnu.org/server-control.html> for how to re-open.

What is the ‘same problem’ here?  IIRC, there were two separate
problems.

Do you mean this one:

  Unknown command: nix fish: nix show-derivation "~/.fr-sqOEpp/....
  module-import-compiled.drv"

I didn't know you were using "guix home", was this also the case in the
original report?  This seems potentially relevant information.  The
exact contents of the home configuration (with personal information
removed and preferably reduced to a minimal test case) could be useful
to investigate the issue.

Or was ‘same problem’ the following
<https://issues.guix.gnu.org/52559#15>?
