I currently can’t nixos-rebuild switch or nixos-rebuild switch --rollback
The problem appears to be independent of generation & configuration.nix as nothing changes either way, so if there’s something I need to change in my configuration, it’s not like I’ll be able to rebuild with the changes AFAIK.
Some errors gotten after attempting to rebuild (full errors at bottom):
Failed to list users: Unit dbus-org.freedesktop.login1.service not found., accounts-daemon.service: Failed to set up mount namespacing: /run/systemd/unit-root/usr/lib/modules: Not a directory, accounts-daemon.service: Failed at step NAMESPACE spawning /nix/store/nld9dik9x218wqjgag90dp56z4gfnrr7-accountsservice-0.6.55/libexec/accounts-daemon: Not a directory, accounts-daemon.service: Failed with result 'exit-code'., Failed to start Accounts Service.
Additionally, while booting up, there are some errors (not the standard ‘OK’) with the message Failed to start User Login Management
I’m using NixOS 20.09 Nightingale on x86_64, kernel version 5.4.114.
