package samba 2:3.5.8~dfsg-1ubuntu2.3 failed to install/upgrade: ErrorMessage: package samba is not ready for configuration cannot configure (current status `half-installed')

[Arv Evans]

Samba failed to install during on-line upgrade from 11.04 to 11.010 release.
This caused a total abort of the upgrade (that sucks because I just spent 5 hours doing the upgrade!).
