"System policy prevents" at login after boot

Asked by Erny Cowan

Lately my Ubuntu 22.04 system locks the loin screen after a reboot. It displays the message "System policy prevents modification of network settings for all users."The keyboard is locked. The cursor moves, but the Cancel and Authenticate buttons do not react.

A couple of times I was able to get in by doing a Safe Mode boot, and then dropping into a normal reboot. But more often even that way I end up with the locked Login.

I tried creating a polkit file in root mode, as one fellow suggested, but that did not help.

I welcome any suggestions. Otherwise I am looking at a reinstall.

Thanks. - Erny

The problem resolved itself, sort of.

I managed to login through safe boot/resume. I 'Forgot' the wifi connection that I was trying to use and re-connected to it. The next reboot went just fine.

I have the same problem on Ubuntu 22.04.3 LTS. I don't think the status should be "solved". Yes, the problem can be probably be worked around by deleting / forgetting the problematic Wifi network. But system should never completely lock the screen for any reason nor show any hard to understand password prompts before the login.
