Perhaps the problem is a failed update?

It looks like you installed some third-party version of the apt package but kept the accompanying and apparently incompatible libapt-pkg5.0 package as it was from Canonical's repositories.

Normally you can force packages to their most recent version available for the current Ubuntu release with:

sudo apt install {PACKAGE_NAME,...}/$(lsb_release -sc)

However in this case Apt itself is affected and broken so you need to:

1. 
   

   Download the packages manually from the package repository (apt, libapt-pkg5.0).

   
   
   
   
   
   1. Make sure that the package's page is for your Ubuntu release (look near the top),
   
   
   2. Scroll to the download section at the bottom of each package's page,
   
   
   3. click the link for your architecture,
   
   
   4. select a suitable download mirror and
   
   
   5. store the package files in a location that you can remember for the next step, e. g. /tmp.
   
   
   
   


2. 
   

   Install the downloaded Deb packages with dpkg:

   
   
   

   cd /tmp
   
   sudo dpkg -i {apt,libapt-pkg5.0}_*.deb
   
   

   
   


3. 
   

   Update your packages to verify that Apt works and make sure that you have the most recent version:

   
   
   

   sudo apt update
   
   sudo apt upgrade
