Hi Felix
How old is your installation (guix describe) and is your system time set correctly?
guix a8353e9
repository URL: https://git.savannah.gnu.org/git/guix.git
branch: master
commit: a8353e9d6b34fd8d42d2e8f14ce844849fe9c293
I never had any issue with my system time and also did not change it at
some point in time.
Any idea why downgrading errors out, this seems more concerning to me...
