I have blank screen after ubuntu(16.04) update and I am trying to fix that with 

 apt-get install --reinstall ubuntu-desktop

but I have unmet dependencies

gnupg : Breaks: python-apt (<= 1.1.0~beta4) but 1.1.0~beta1ubuntu0.16.04.2 is to be installed ubuntu-desktop : Depends: checkbox-gui but it is not going to be installed

I tried 

apt-get update

and

apt-get upgrade

how can I resolve that dependency without removing gnupg because as far as I remember if I delete that I can break system packages

  • A quick look at https://packages.ubuntu.com/search?suite=all&searchon=names&keywords=python-apt shows your sources are outdated, you have invalid sources, or are using a mirror that is outdated (https://launchpad.net/ubuntu/+archivemirrors). I'd apt-cache policy python-apt and investigate your source(s) for it. FYI: you didn't provide architecture so I assumed amd64/i386 so your messages should say 1.1.0~beta1ubuntu0.16.04.8. Something you've added from 3rd party sources could also be your issue – guiverc Feb 22 '20 at 00:43

    Does this answer your question? How do I restore the default repositories? – N0rbert Feb 22 '20 at 11:02
