I have an old Dell XPS 13 laptop with NixOS as its only OS. I haven’t used it in a while, and after that latest update it fails to boot. After selecting the latest generation in
systemd-boot it shows the message
EFI sub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path, and nothing happens after that. What is more bizarre is that the previous generations also have stopped booting.
I’ve tried the following:
- Setting most of the kernel cmd arguments from this page (without any effect)
- Booting from an installation media, mounting system disks to
NIXOS_INSTALL_BOOTLOADER=1 /nix/var/nix/profiles/system/bin/switch-to-configuration bootcommand (no help)
nixos-installworked! It created a new generation which has booted successfully
nixos-rebuild switch --upgrade from the running system resulted in the same broken boot state. Afrer pocking around, I’ve found that if I run
nixos-install right after
nixos-rebuild switch, everything works fine.
I spotted a difference between generation labels created by
The former says it’s
NixOS 22.11.22…, while the latter creates
NixOS 23.05pre…. After that, I switched from the unstable channel to the stable one, and now it all works fine.
The last generation that worked was created on 2022-12-02 with the label
NixOS 23.05pre430779.e76c78d2068, and the broken one was on 2023-02-02
NixOS 450086.e1e1b192c1a, if that’s any help.
