Before upgrading read the following:


Normal Procedure
  1. Make sure that the software for your current version of Ubuntu is fully up to date.
  2. Check your upgrade policy with the software upgrade tool.
    You can be advised about upgrades for any new version or stable LTS versions only.
  3. Click on the gear icon on the top panel, then click on System Settings, then click on Software & Updates and then click on the Updates tab. See screenshot below.
  4. Make sure that you are using an official software repository channel.
  5. Backup any special personal package archives (PPA) and then remove them because most of the errors during an upgrade are due to the use of custom PPA's. See PPA help links below.
  6. Then type sudo do-release-upgrade or sudo do-release-upgrade -d in a terminal.
  7. Follow the instructions. You may have to open inetkey to help the upgrade get started.

PPA Help

To add the Y-PPA manager to your software sources, type the following in a terminal:

sudo add-apt-repository ppa:webupd8team/y-ppa-manager
sudo apt-get update
sudo apt-get install y-ppa-manager

Then type, PPA in the dash to launch the software. See screenshot below.

See the note below from Jan at AIMS.

Behind a (compulsory) proxy, on trusty, you have to use sudo -E to preserve the proxy for apt-add-repository, apt-get update, install.
