Have the same issue upgrading from bionic to cosmic. Updating appstream to the version from cosmic workedaround the problem.
Please backport fix to bionic so that other people will be able to upgrade using the Ubuntu normal upgrade process. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to appstream in Ubuntu. https://bugs.launchpad.net/bugs/1785498 Title: g_atomic_ref_count_dec: assertion 'g_atomic_int_get (arc) > 0' failed Status in AppStream: Fix Released Status in appstream package in Ubuntu: Fix Released Status in glib2.0 package in Ubuntu: Invalid Status in appstream package in Debian: Fix Released Bug description: When running sudo apt update in a terminal I sometimes see the following message printed within the output.
