Ubuntu 20.04 LTS (Focal Fossa) has been released, so I've prepared a list of top things to do after installing it.
Whether you're new to Ubuntu or a long-time user, use this list of top things to do after installing Ubuntu 20.04 LTS, to help you get most things set up so you can enjoy your new Ubuntu 20.04 LTS desktop, and customize it to accommodate your needs.
I obviously don't know what each user does after a fresh Ubuntu installation, so this list contains the things I do that I think would benefit others. Use the tweaks that you find useful for your use case.
