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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1785498 Title: g_atomic_ref_count_dec: assertion 'g_atomic_int_get (arc) > 0' failed To manage notifications about this bug go to: https://bugs.launchpad.net/appstream/+bug/1785498/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
