Updating Ubuntu

Do a fresh install!

If your ~/home is on a separate partition, that does not need to be reformated and can be kept!

Although why not take the opportunity to start fresh!

Sotware Updater

Terminal

sudo apt update
sudo apt upgrade
sudo do-release-upgrade # -c to check for upgrades

After the updates

  • Some ppas and software might have been removed

Can be launched with software-properties-gtk (e.g. with ssh -X or -Y) * Remove anything from "other software" and "authentication" that has been disabled by the upgrade and make a note of which.

Terminal

  • apt update should now run without any errors or warnings
  • Reinstall those that were removed
