Yes, thank you. That was my starting point. I also did a search for the error and that’s were I got the “sudo apt-get -f install” and the terminal command for the install. But either method gets the same result.
Found a work around / answer from ‘Linux Mint Forum’. “For Linux Mint 20 instead use the Ubuntu 20.04 download, until such time that they add Mint 20 in their distro selector. The Ubuntu 20.04 download installs fine on Linux Mint 20.”
