bug#52559: guix pull fails with `Unknown command: nix fish: nix show-derivation "~/.fr-sqOEpp/....-module-import-compiled.drv"

[Grigory Shepelev]

Same problem is:

Computing Guix derivation for 'x86_64-linux'... |ice-9/read.scm:126:4: In procedure read-string: gnu/packages/virtualization.scm:643:1: invalid character in escape sequence: #\return
guix pull: error: You found a bug: the program '/gnu/store/kms78b5wzmp763lljsazbp8v8a88p1z8-compute-guix-derivation'
failed to compute the derivation for Guix ...

on "guix pull".

All my config are right there: https://git.sr.ht/~shegeley/config/tree/master/item/home/core.scm

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>?
