ReleaseUpgrades

Revision 1 as of 2012-01-26 18:49:36

Clear message

This is the beginning of a living specification for how Ubuntu should present release upgrades. It is part of Ubuntu’s overall software handling.

  • Packages affected: release-upgrader

Invitation to upgrade

You should be able to upgrade from one of three access points: Software Updater, Ubuntu Software Center, or the Ubuntu installer.

If you choose to upgrade from either Software Updater or Ubuntu Software Center, you should first see an “Upgrade to Ubuntu {new version}” dialog containing information about the new version (bug 885720), the price of “Free”, and “Cancel” and “Upgrade Now” buttons.

Offering backup/recovery

We would like to maximize the proportion of people who can successfully use their computer after attempting an upgrade.

To do that, we would like to offer a simple backup or recovery system (probably not both) that lets people restore/recover from a failed upgrade.

This might involve:

  • inviting people to back up their system files to an external disk or USB key
  • installing a recovery partition on the same disk as is being used for the installation, and writing a minimal disk image there
  • changing the MBR so a specific key always starts from the recovery partition.
