This bug report is actually about an upgrade from Ubuntu 14.04 to Ubuntu 16.04 where dpkg is being upgraded from 1.17.5ubuntu5.8. That version of dpkg does not have support for the "-await" alias variants and dpkg was updated after libglib2.0-0 so that package upgrade failed. This is fallout of the changes in bug 1780996. The fix is to make the packages changed in bug 1780996 pre-depend on dpkg greater than or equal to 1.17.21.
It is also worth investigating the archive for other packages in Ubuntu 16.04 that use "-await" but do not pre-depend on dpkg. -- 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.
