This bug is also happening to me in 20.2 and 21.4. I'm trying to back up to another HDD that is connected inside my computer (not external).
** (deja-dup-preferences:30681): CRITICAL **: deja_dup_config_location_add_volume_full: assertion `uuid != NULL' failed Clearing ~/.cache/deja-dup or going into dconf-editor and changing settings from 'volume' to 'normal' don't fix the problem. Once I get the above error, the program opens, but the buttons are all grayed out (excluding help). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/569418 Title: deja-dup fails on backup to external drive with g_file_get_uri: assertion `G_IS_FILE (file)' failed To manage notifications about this bug go to: https://bugs.launchpad.net/deja-dup/+bug/569418/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
