Thank you for your report. If you're trying to downgrade from 5.6 to 5.5, then this is not an automatically supported path, will require manual intervention as you discovered, and thus is not a bug. See the 14.04 release notes: https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes#MySQL
If you're reporting something else, then please explain and then change the bug status back to New.
