So I'm an Ubuntu noob trying to broaden his OS horizons. It's been going well until just now when I started looking at some games to install. I downloaded Urban Terror, but I can't seem to get it running. UrTUpdater won't run for me, and I've looked around at other people having problems but none of their suggestions helped. I've tried running it from terminal, but I always either get: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory, or No such file or directory even though I type it in right. I tried redownloading it many times but no change. I'm sure I'm just making a rookie mistake somewhere but this is frustrating.
