No I did not play around with branches. What I did was
- changed my config
- reconfigured
- rebooted
- failed
- booted second last config
- fixed config
- reconfigured
- rebooted
- OK
- pulled
- added cups
- reconfigured
---->>> ERROR
I just tried again. Did a
GUIX_PROFILE="~/.guix-profile" && . "$GUIX_PROFILE/etc/profile"
hash guix
guix system reconfigure .../config.scm
Same error.
Is there a way to find out what goes wrong? And why I have something
installed that is newer than what I get over the guix channel?
