I verified this by using ubuntu-drivers in a chroot on a system with
nvidia but "runtimepm" isn't supported on my system so I had to change
the check for it from "if packages[p].get('runtimepm'):" to "if True:".
After doing that I received the original Traceback:
...
File "/usr/bin/ubuntu-drivers", line 161, in command_install
pm_fd = open('/run/nvidia_runtimepm_supported', 'w')
PermissionError: [Errno 13] Permission denied: '/run/nvidia_runtimepm_supported'
Now for the verification:
