[Bug 898278] Re: Upgrade menu option should not appear for old releases

[Launchpad Bug Tracker]

This bug was fixed in the package ubiquity - 2.9.22

---------------
ubiquity (2.9.22) precise; urgency=low

  * ubi-partman:
    - Avoid crash when calling contextual menu on a partition list item.
      (LP: #936115)
    - Add logic to parse the current and new version number and only
      allow reusing an existing install if the target is older than the
      media. (LP: #898278)
  * ubi-console-setup:
    - To avoid issues when quickly changing the selection (easily done by
      using the keyboard), add a 600ms delay to any user action, reset with
      any further action.
      The UI is also now set_sensitive(False) while waiting for a UI
      refresh.
      This should be enough to limit or get rid of (LP: #645449)
  * Automatic update of included source packages: netcfg 1.68ubuntu12.

Title:
  Upgrade menu option should not appear for old releases

Status in “ubiquity” package in Ubuntu:
  Fix Released
Status in “ubiquity” source package in Precise:
  Fix Released

Bug description:
  As documented in bug 891711 if you insert a bootable disk with a
  previous release of Ubuntu, say 11.10, into a system running a later
  release of Ubuntu (12.04) you are presented with an option to
  "Upgrade" from the new release to the old one.  This reinstalls Ubuntu
  while preserving your home and installed applications.  However, this
  was not an envisioned use case (and subsequently is not tested) and is
  problematic as the kernel from the new release is not removed.

  The option to upgrade from a new release to an old release should not
  appear in Ubiquity.
