Fix our server ASAP after stupid upgrade by amateur

Our server run Debian and latest version of Plesk. Today we messed up. We did a: apt-get upgrade and then Plesk and other stuff stopped working like mail and mysql. We now need someone to fix our mistake quickly! What we tried to accomplish was installing UnRAR and a library was missing and there for we did the upgrade command. It could be as easy as getting the mysql server online since that is what Plesk is complaining about when trying to access it. We also want mtop installed and a few other smaller utilities. But the Plesk, mail etc must be fixed right away! Demands: You MUST have at least 10/10 here on GAF or we won't let you inside our server. No pre-payments You must have very good knowledge and know what you are doing!
