Hi,
When I set up a systemd-nspawn container via NixOS containers option, I found that the login command always fails with the following error:
> sudo machinectl login <container>
Failed to get login PTY: Unit container-getty@1.service not found
Using shell command is okay but that’s different from a login shell.
Does anyone have any clues on how to fix this error?
I have the exact same problem.
nixos-container root-login is OK but nixos-container login is not:
$ sudo nixos-container login <container>
Failed to get login PTY: Unit container-getty@1.service not found.
I am using 25.05
stdout of command without sudo
$ nixos-container login my-container

nixos-container login my-container was working fine for me for a little bit then I started getting the exact same errors as you. I haven’t figured out a fix but I did find that sudo nixos-container root-login my-container does work.
