After Upgrading to ubuntu 20.04, I wanted to uninstall playonlinux and it shows errors:
$ sudo apt-get purge playonlinux

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
wine : Depends: wine1.6 but it is not going to be installed
wine1.6-i386:i386 : Depends: wine1.6:any (= 1:1.6.2-0ubuntu14.2)
Recommends: libp11-kit-gnome-keyring:i386 but it is not going to be installed
Recommends: wine-gecko2.21:i386 but it is not installable
Recommends: wine-mono0.0.8:i386 but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
$ sudo apt --fix-broken install
This command shows error. Because wine 1.6 is not compatible with ubuntu 20.04

E: Sub-process /usr/bin/dpkg returned an error code (1)
And ubuntu software updater was not working. So, it was a disaster.
I found the solution, and I have added the answer.
