I second this. Since today I’m getting a very similar error when rebuilding, even though I didn’t change anything besides new fonts (which I reverted but still get the error)

 sudo nixos-rebuild switch --flake .#nixos

It looks like the assertion it’s failing on was added in the latest systemd version bump (about 3 weeks ago):

It also looks like I can only reproduce this after resuming from hibernation. I don’t run into this problem after rebooting (until my system goes into hibernation again).

Bug fix is here, but it’s unclear whether it’ll land in 25.05 which goes end-of-life very soon

@nito and @yurix73 can you confirm if rebooting before trying nixos-rebuild again works around this issue?

Hi, for me it works now after rebooting. Thank you!

ok so i did some testing and the issue only happens if you return from hibernation and try to sudo nixos-rebuild switch --upgrade after you run that command sudo nixos-rebuild swtich will be broken for the whole hibernation session

it sound to be the same as in nixos/systemd-boot: Failed to install bootloader if /boot/loader/random-seed does not exist · Issue #461676 · NixOS/nixpkgs · GitHub
