Update to my comment #8: The upgrade from 14.04 to 16.04 failed later again on package gconf2
dpkg: error processing package gconf2 (--configure): dependency problems - leaving triggers unprocessed dpkg: dependency problems prevent processing triggers for gconf2: gconf2 depends on python:any; however: Package python is not configured yet. And many other packages. This PC has been installed with Ubuntu 12.04, then upgraded to 14.04, and now upgrading to 16.04 fails with the bug described in this tracker item and leaves the system not upgraded and not upgradable. Reverting now to 14.04 from backup and postponing upgrade to 16.04. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to glib2.0 in Ubuntu. https://bugs.launchpad.net/bugs/1784065 Title: upgrade from 14.04 to 16.04 fails due to `interest-await' in trigger Status in glib2.0 package in Ubuntu: Triaged Bug description: Package failed to install.
