Upgrade from 18.04 LTS to 20.04 LTS fails due to `Unofficial software packages not provided by Ubuntu`

When trying to upgrade from 18.04 LTS to 20.04 LTS on my PC, the process fails due to Unofficial software packages not provided by Ubuntu. I tried to find the broken packages using grep Broken /var/log/dist-upgrade/apt.log and I got this:
