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
