Hi,
since I can not use MATE Desktop now
I am considering to rollback.

It is not a question of packages like
guix package --rollback

but a question of MATE Desktop

is this the right command to rollback one Generation of the system,

because MATE is updated by the

"$ sudo guix system reconfigure /etc/config.scm" ?

sudo guix system roll-back

AFAIU this command rolls back "guix pull" and the guix system wide updates.


Kind regards

Gottfried

This is the right command. It rolls back the system generation only, not the guix pull profile, which would be rolled back with "guix pull —roll-back". You don't need to roll it back though, only the system profile where MATE is installed.

I think the system roll-back only moves your current system generation
back by one. You still have to reboot.

You can also boot into the older generation manually, but the
roll-back command makes it stick (and eventually overwrites newer
generations).

I don't think the command affects the state of 'guix pull' (that's why
the roll-back step sometimes downloads additional package versions)
but I'm kinda new.

Kind regards
Felix

No, it only rolls back the system wide updates. `guix pull` works (by
default) on the *profile* in `~/.config/guix/current`. It is a private
profile of the user calling `guix pull` and is not altered by `guix
system ...` commands

Best,
Wojtek

That may be a matter of perspective. It can make sense, I think, to
roll back a non-working Guix when a user wishes to reconfigure before
Guix is fixed.
