Comment 9 for bug 996166

It actually seems like it might be best to *not* fix it in 12.04.
* You can easily add a 'salt' metapackage to the ppa which would fix it
* there is no 'salt' or salt-minion package in 12.04 its not explicitly *wrong* there.
* There isn't an easy way to make this change without breaking someone's 12.04 stuff that included a package named 'salt' in the archive.

Can you just change the archive?
