> An SRU of nspr to make CD-based upgrades work better from 10.04 to 12.04
> has caused failures in other cases where users have continuously upgraded
> their systems from Ubuntu 9.04 or earlier and as a result have had old,
> obsolete evolution packages held back. These users can now not upgrade at
> all using update-manager.

> [Test case]
> 1. Fish an old Ubuntu 9.04 CD out of the drawer and install in English.
> Make sure that the language-support-en package and
> language-support-translations-en are installed.
> 2. Manually upgrade to 10.04. Check that language-support-en is still

> 3. Run update-manager -d to upgrade to 12.04. Verify that this upgrade

> 4. Enable -proposed, so that precise-proposed will be used in the
> upgrade to 12.04.
> 5. Run update-manager -d again. Verify that the upgrade now succeeds.
