Polkit auth broken after update (Pidfd not supported on kernel 5.15)

Support System Updates

In my case, just fixing the polkit-agent-helper SUID permissions wasn’t enough. I did it with:

sudo chmod 4755 /usr/lib/polkit-1/polkit-agent-helper-1

But I also had to mask the polkit-agent-helper socket:

sudo systemctl stop polkit-agent-helper.socket
sudo systemctl mask polkit-agent-helper.socket

Otherwise, the problem persists.

Cheers and thanks a lot.
