bug#44115: “guix import -r“ fails with Bactktrace instead of error

[zimoun]

Dear,

Compare:

  $ guix import elpa foo
  guix import: error: failed to download package 'foo'

with:

  $ guix import elpa foo -r
  Backtrace:
             4 (primitive-load "/home/simon/.config/guix/current/bin/guix")
  In guix/ui.scm:
    2116:12  3 (run-guix-command _ . _)
  In guix/scripts/import.scm:
     120:11  2 (guix-import . _)
  In guix/scripts/import/elpa.scm:
     103:16  1 (guix-import-elpa . _)
  In guix/import/utils.scm:
     431:36  0 (recursive-import "foo" gnu #:repo->guix-package _ #:guix-name _)

  guix/import/utils.scm:431:36: In procedure recursive-import:
  Wrong number of values returned to continuation (expected 2)



Idem with the importers: ’hackage’, ’pypi’, ’cran’, ’crate’ and ’opam’.
Note the special mention to ’gem’:

  $ guix import gem kikoo -r
  #f


All the best,
simon
