I've recently installed 12.04 on my PC but I am finding that it takes an eternity to install software using the software center. My PC has more than enough power to handle this (I'm running a 64 bit machine), so it's not a hardware issue. I've seen a similar thread to this but no clear answer on how to remedy the problem was given. It took me 30 minutes to install a game I downloaded, this was on top of the download time, and my PC was effectively unusable during this period. Other software I've downloaded (Skype, Wine etc) were slow to install. Any help would be greatly appreciated.
