Hello GNU Guix Team!

Guix tells me, that I found a bug and gives me the following output:

Perhaps I should describe the version I am at?:

~~~~START~~~~
$ guix describe --format=channels
(list (channel
         (name 'guix)
         (url"https://git.savannah.gnu.org/git/guix.git")
         (branch "master")
         (commit
           "3f83dc5587573f173b1f61864c9b510f05de84b1")
         (introduction
           (make-channel-introduction

               "BBB0 2DDF 2CEA F6A8 0D1D  E643 A2A0 6DF2 A33A 54FA")))))
~~~~~END~~~~~

Hope it helps!

Meanwhile I guess I could try to do `guix pull --no-substitutes` or update guix 
itself running `guix pull && guix package -u` as root. But I am not sure I 
should do that, in case more information is needed to help with the bug report?

Best wishes,
Zelphir
