Ubuntu Upgrade failed — Should I reinstall?

Ubuntu, you have let me down in a most heinous way. For months, your update manager has been telling me to upgrade from 7.04 to 7.10. When 8.04 came out, you didn't offer me a direct upgrade path to the very latest, I had to upgrade one version at a time. The upgrade from 7.04 to 7.10 took about 5 hours and a handful of prompts about keeping configuration changes. I figured I might as well open the update manager and upgrade again to 8.04 LTS.
