Hey there!

I use these:
$ guix pull
$ sudo -E guix pull system reconfigure /etc/config.scm

I did have some problems and the upgrade only work fine with "sudo -E".

Could you describe more precisely what you did (‘guix system
reconfigure’? what was the output of ‘guix describe’?) and what you see
(you rebooted after reconfigure? what do you see on the screen
precisely?).

Thanks in advance,
