update-manager crashed with RuntimeError in <module>()

Binary package hint: update-manager

reproducible when starting update-manager from network ssh. the apport thing starts on the xorg of that box (I got both boxes next to each other). I've heard there is a cli version of update-manager and that it's better to use that compared to apt-get

Would be nice with some user friendlyness here, dont throw exception to terminal and dont trigger apport... instead just print what the CLI command for update-manager is.
