It is 2026, and the broken NetworkManager.state file is still an issue! After removing that file fixed everything, I figured out that I could have solved the problem without becoming root using:
But, there's no way for anyone to ever figure that out as NetworkManager never mentions the NET setting!
nmcli dev wififailed to scan for stations but gave no error messages.nmcli,nmcli dev, andnmcli generalall showed that wlan0 was unmanaged which was not true and a red herring. The more important fact was that "NET" was disabled and so being managed or not didn't matter and could not be changed.nmcli dev set wlan0 managed yesgave no error message even though it failed because NET was off.nmcli radiosaid that WIFI was disabled, which was true, but irrelevant since it cannot be changed when NET is off.nmcli radio wifi ongave no error message even though it, too, failed to work.Thank goodness I ran across this gist as I was tearing my hair out.
