OK, Based on the descriptions of other in the duplicate reports, and based on my experience, all you have to do is restart your system to resolve the problem. Most probably, what Michael suggested would work ( $ killall software-center...).
So the main issue is to find what caused the problem to begin with. To that end, I reinstalled a fresh copy of natty. I started software center and added 5 programs waiting in the stack to be installed. The first one (vlc) installed. The second one (restricted extras) finished downloading and started installing. A new window poped up (to accept the EULA licence) and after accepting terms and such, an error message came up "Failed to download packages" (see screenshot). I also attach the debug info and the software-center cache right after getting the error message I remember this is the same error message I got the first time, but the first time I closed the program cause it was not showing any progress. This time I didn't close it for about 30 minutes. After re-opening it, all the programs in the stack where properly installed (although the installation status did not update when software center was running). Hope this helps... ** Attachment added: "Screenshot.png" https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/772549/+attachment/2097228/+files/Screenshot.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772549 Title: software-center blank screen on fresh natty 11.04 install -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
