Ubuntu – 16.04 click unmet dependancies

16.04click-packagesdependenciespackage-management

I am in a situation where package click is broken. I have tried many things, but did not manage to fix it.

$ sudo apt dist-upgrade 
Reading package lists... Done

You might want to run ‘apt-get -f install’ to correct these.
The following packages have unmet dependencies.
 click : Depends: python3-click-package (= 0.4.43+16.04.20160203-0ubuntu2) but 0.4.43+16.04.20170613-0ubuntu1 is installed
E: Unmet dependencies. Try using -f.

Obvioulsy sudo apt-get -f install does not fix it. Nor trying to remove python3-click-package.

Any help welcomed.

$ apt-cache policy click python3-click-package

I can not even remove the package:

$sudo apt-get -f purge click

Managed to sort it out with:

sudo apt install python3-click-package=0.4.43+16.04.20160203-0ubuntu2 gir1.2-click-0.4=0.4.43+16.04.20160203-0ubuntu2 libclick-0.4-0=0.4.43+16.04.20160203-0ubuntu2

I built that command step by step following the messages in the unmet dependencies... Then I was able to fully remove the click package...

sudo apt purge click
