Gnome-shell-dbgsym is out of date

[Bram Stolk]

I am using bionic updates repository, and I can't install the debug symbols for gnome-shell.

gnome-shell-dbgsym Is out of date

gnome-shell-dbgsym : Depends: gnome-shell (= 3.28.3+git20190124-0ubuntu18.04.1) but 3.28.3-0ubuntu0.18.04.4 is to be installed

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.

[Daniel van Vugt (vanvugt)]

Also, it appears the problem is arising from your existing debug package being a higher version than the binary package not yet installed. I don't know how to reproduce this situation without intentionally breaking the system...

Please try this as a fix:

  sudo apt update
  sudo apt install -f
  sudo apt update
  sudo apt full-upgrade

I do not have gnome-shell-dbgsym installed.

Same problem, after doing those steps.

There is *no* old version of dbgsym installed. When I try to install it:

$ dpkg --list | grep gnome-shell

ii gnome-shell-common

the GNOME graphical shell

It sounds like your system is somehow configured to get debug packages from proposed, but binary packages from updates.

My system was indeed mis-configured. Thanks for helping, I apologize for the distraction.
