Hello Guix,
This is not a request for help, but just for reference, so you may skip it.
Recently I fell pray to a hardware issue which rendered one of my guix
machines stuck and unable to upgrade. Issue #41362 seems related and user
also confirmed a hardware issue. Nonetheless, after solving the imediate
hardware problem I was stuck with a system which would refuse to pull
newer generations.
I first tried to roll-back guix pull, system and package to no avail.
I've tried time-machine as well and it did not help. I've also tried a
'--bootstrap' guile flag when pulling and got an unrelated issue. I was
about to bust the system and reinstall when guix gc came to rescue.
The procedure was simple enough but it took me some time to figure: switch
guix pull to last good generation; delete the one where the corruption
started; garbage collect everything; pull again.
