Until this is fixed an option were to switch to the old generation where it still worked, start it and switch back to the current generation. Is there an option to run a program in a specific generation without completely switching to it? I didn't found any so far. I know that's a real hack but at least that way I could have my files synchronized without too much effort until the bug is fixed. Another question I have is: can I install version 3.1.3 of nextcloud-client in the current environment (without switching back to some old commit)? When I try to do so, I get > guix install: error: nextcloud-client: package not found for version 3.1.3 because version 3.1.3 was replaced by 3.2.0. Cheers (and a happy new year!) Alex
