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')

I do not know if this is a bug. The upgrade manager for Ubuntu 11.10 could not install Samba and said I should file a bug report. However, I am not familiar enough with the system to understand what went wrong, why, and its consequences.
