How to Upgrade Ubuntu 18.04 LTS or 19.10 to Ubuntu 20.04 LTS “Focal Fossa”

Ubuntu 20.04 LTS introduces numerous new features and improvements, so upgrading is probably the first thing you’ll want to do. Well, the good news is upgrading from either Ubuntu 18.04 LTS or Ubuntu 19.10 is easy. But before I guide you through the upgrade process, ensure your system is up to date. After you’ve installed all available updates, open the Software & Updates utility, go to the third tab called “Updates” and make sure the “Notify me of a new Ubuntu version” drop down menu is set to ???For long-term support versions??? on Ubuntu 18.04 LTS or “For any new version” on Ubuntu 19.10.
