I'm actually being generous above; a user is much more likely to do:
``` $ ubuntu-drivers install nvidia-driver-410 usage: ubuntu-drivers [-h] [--package-list PATH] [--gpgpu [driver[:version][,driver[:version]]]] [<command>] ubuntu-drivers: error: unrecognized arguments: nvidia-driver-410 ```
which is an even worse error message. So `list`s output should probably also guide the user towards the correct installation method.
