I recofigured the system without an error one hour ago (introduced seperate home filesystem) and now, when I try to add the cups service (I did a guix pull in between as well) I get: > guix system: error: aborting reconfiguration because commit bd2aa8031babdca5f574fca52e025d6794f08d82 of channel 'guix' is not a descendant of 7f974548ac20cab88b9bb589a5e1d85ee3b8d337 > hint: Use `--allow-downgrades' to force this downgrade. I have no clue what caused that error therefor I also don't know if it's a good idea to allow downgrades. ... or what es to do to resolve the issue. Cheers, Alex
