Hello,

I have a machine running Ubuntu Server 18.04.4 LTS and I get this error after:

XXXX@cooookie:~$ sudo apt-get update

Reading package lists... Done
E: Problem executing scripts APT::Update::Post-Invoke-Success 'test -x /usr/bin/apt-show-versions || exit 0 ; apt-show-versions -i'

Any clues?

Thanks in advance!
