Linux Mint 20 Ulyana

I upgraded my desktop to Linux Mint 20 Ulyana over the weekend.

Edit your package repository. Replace tricia with ulyana, and bionic with focal.

vim /etc/apt/sources.list.d/official-package-repositories.list

Run update first.

apt update -y
apt upgrade -y

Perform upgrade to Linux Mint 20. When prompted, choose default.

apt dist-upgrade

Reboot.

reboot

cat /etc/os-release.
