Hi, I just installed Kubuntu for the first time. I am trying to get a few packages, but while doing that, I stopped it by closing it. Now it complains about some other program using it, so I can't get anymore packages. I tried to kill all the processes e.g. adept, apt-get etc from command line and from ksysguard as well ; but that doesn't help. Can someone please help me with this? Thanks Sanhita
