MySQL Package problem after update

view full story

http://askubuntu.com – I recently installed the newest version of Ubuntu (12.04 LTS 32 bit). Afterward, I opened up Update Manager and got the following error: An unresolvable problem occurred while initializing the package information. Please report this bug against the 'update-manager' package and include the following error message: 'E:The package mysql-server-5.5 needs to be reinstalled, but I can't find an archive for it.' I don't use MySQL-server, and I don't know how to fix this. After I get this error, package manager closes leaving me unable to update anything. (HowTos)
