Unable to fix unmet dependancies apt

Question

Hay everyone

I am running Ubuntu 20 and I am facing some problems with 'apt'. I have been unable to fix the following error from apt after a wring installation of the Robotic Operating Systems

sudo apt-get upgrade

You might want to run apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 python2 : PreDepends: python2-minimal (= 2.7.17-2ubuntu4) but 2.7.18-3 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I understand that I should install the version of python 2.7 but even when I run the suggested command sudo apt --fix-broken install I get the following error
