I’m running Unity on an Ubuntu 19 derivative (AntiX). When I start Unity Hub I get the following messages:
(unityhub-bin:24765): libappindicator-WARNING **: 22:33:48.240: Unable to get the session bus: Unknown or unsupported transport “disabled” for address “disabled:”
(unityhub-bin:24765): LIBDBUSMENU-GLIB-WARNING **: 22:33:48.240: Unable to get session bus: Unknown or unsupported transport “disabled” for address “disabled:”
Unity Hub does start and things do seem to work, I’d just prefer things start cleanly so I don’t get bit later by something mal-configured.
