How to upgrade to Ubuntu Linux 18.04

With Ubuntu 18.04 Linux, the next long-term support version, coming out shortly, it’s time to go over how to upgrade this popular Linux distribution.
First, keep in mind that this Ubuntu will not look or feel like the last few versions. That’s because Ubuntu is moving back to GNOME for its default desktop from Unity. The difference isn’t that big, but if you’re already comfortable with what you’re running, you may want to wait a while before switching over.
Eager to make the move? Well, before starting, you should backup your existing Ubuntu desktop. There are many ways to backup Ubuntu. My favorites for complete system backups are Ubuntu’s default Déjà Dup and CloneZilla. Whichever method you use, you should also check the restore to make certain your backup is good.

Next, if you want to do this from the GUI, take the following steps:

  • Open the “Software & Updates” setting in System Settings.
  • Select the third tab, called “Updates.”
  • Set the “Notify me of a new Ubuntu version” dropdown menu to “For any new version.”
  • Press Alt+F2 and type in “update-manager -cd” (without the quotes) into the command box.
  • Update Manager should open up and tell you: New distribution release ‘18.04’ is available.
    • If not, you can also use “/usr/lib/ubuntu-release-upgrader/check-new-release-gtk”.
    • Click Upgrade and follow the on-screen instructions.
