This might be the upgrade issue I described in #965210. If it is, the workaround is to reboot, or to log out and back in. #965210 is very similar to the old bug #699447 in experimental, but with different versions and paths involved. > polkitd logs Log messages from your polkit agent (whatever package provides polkit-1-auth-agent, for example GNOME Shell, polkit-kde-agent-1 or lxpolkit) would help to confirm whether it's #965210. If it's #965210, you'd see something like this (quoting from #699447, the message might be a bit different in testing/unstable): Cannot spawn helper: Failed to execute child process "/usr/lib/policykit-1/polkit-agent-helper-1" (No such file or directory) If you get a message similar to that during the failure to authenticate, then this is probably a duplicate of #965210. smcv
