Possible Duplicate: Dropbox fails to install, stuck at 99% I just installed Dropbox via Ubuntu Software Center, and the known crash of 99%, which was in Ubuntu Software center, happened. I want to remove Dropbox completely since something went wrong, but I can't. When I start my Ubuntu, it starts a process which eats up all of the CPU. In Ubuntu Software Center, there is a process "Searching Applying Changes", but nothing really happens. When I'm trying to uninstall Dropbox, nothing happens, since the seaching thing is "first". Please, I'm asking for a option which doesn't include proper reinstallation of Dropbox, only of getting rid of it, and without reinstalling the whole Ubuntu system (format, chaos etc).
