Hmm, gnome-shell-dbgsym (3.28.3+git20190124-0ubuntu18.04.1) installs just fine if you install it afterwards.
AFAIK most packages avoid this problem by automatically uninstalling debug symbol packages before updating the binary packages (which is annoying in itself). It appears that didn't happen in your case. Possible workaround: Just uninstall gnome-shell-dbgsym, update the system and then reinstall gnome-shell-dbgsym. ** Tags added: bionic ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1819816 Title: Gnome-shell-dbgsym is out of date To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1819816/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
