Hey guys, I've been using Ubuntu for about a year now and I have never had this problem. I just installed Ubuntu 12.04 LTS on my Dell Inspiron Duo 1090. I was installing some basic software the I commonly use from the Software Center. The last program that I tried to install was Dropbox. For some reason, even after restarting, the software center is stuck "Searching Applying Changes".
I tried uninstalling and reinstalling via terminal. No such luck. Any advice guys?
