Failed to synthesize after upgrade to 23.11

Help

Hello,

I just wanted to update to 23.11 from 23.05 and I get this strange error:

sudo nixos-rebuild switch --upgrade                              Sat Mar 16 10:54:40 2024

I wanted to see what files are there when the system-288-link is missing:

ls /nix/var/nix/profiles/                                        Sat Mar 16 11:08:41 2024

per-user                                system-289-link
system

Does anyone has an idea what might have happend here?
Thanks in advance!

Does anyone have any thoughts on this? I still couldn’t figure it out…

Switching back to the channel 23.05 I now get this error:

I fixed it by renaming the folder /nix/var/nix/profiles/system-288-link.tmp-4121466-1819997941 to /nix/var/nix/profiles/system-288-link
