Dear GNU Guix developers,

I just tried to install guix on top of a fresh debian10 system, which
has been installed from debian-live-10.0.0-amd64-gnome.iso and updated.

The guix install script fails in function chk_gpg_keyring(), although
the key is present.

If I remove the discard redirection >/dev/null 2>&1 from the gpg
command, the following message occurs:

 gpg: keyblock resource '/root/.gnupg/pubring.kbx': No such file or directory
 gpg: Fatal: /root/.gnupg: directory does not exist!

Of course these files do not exist, as I imported the key to the user
account, not to the root account. Then I executed the script as user,
using sudo.

This procedure works fine on trisquel7 or 8, but it fails on debian10.

I wonder why ‘sudo gpg’ does not make a difference between being called
via sudo versus being called as root.

Do I use debian the wrong way?

best regards
Kai
