I`m unable to reproduce it anymore. Except in the case for the openvpn source from this address: http://build.openvpn.net/debian/openvpn/stable
Managed to see the error when opening the software update from terminal via `software-properties-gtk` -> in the attached file and below. Apparently there is some issue with the openvpn repo and the error handling in such cases is failing somehow: ``` $ software-properties-gtk Traceback (most recent call last): File "/usr/lib/python3/dist-packages/softwareproperties/gtk/DialogCacheOutdated.py", line 86, in on_pktask_finish results = self._pktask.generic_finish(result) gi.repository.GLib.Error: pk-client-error-quark: W: GPG error: http://build.openvpn.net/debian/openvpn/stable bionic InRelease: The following signatures were invalid: EXPKEYSIG 8E6DA8B4E158C569 Samuli Seppänen (OpenVPN Technologies, Inc) <sam...@openvpn.net> E: The repository 'http://build.openvpn.net/debian/openvpn/stable bionic InRelease' is not signed.
