Hi,

Now we know!  ‘guix-daemon’ hit the assertion failure above, which is a
bug.  That happens because while talking to the ‘guix authenticate’
subprocess, said process emits that warning:

  /gnu/store/…/bin/bash: warning: setlocale: LC_ALL: …

and guix-daemon reads the leading “/” and explodes, somehow.

However, it seems you’re running guix-daemon from Guix 1.2.0,
which is quite old, and chances are that the bug you hit has long been
fixed.

Could you try upgrading guix-daemon?
