Update issue

view full story

http://www.ubuntux.org – I'm sure this has been addressed somewhere, but I'm having trouble finding it. I've just started using Ubuntu 9.10 so if this is an idiot question, that's my excuse (NOOB). Everything's going great except that I keep getting an update alert in my app panel and when I check for updates get the following: Failed to fetch http://ppa.launchpad.net/awn-test/ppa/ubuntu/dists/karmic/main/binary-i3... 404 Not Found Some index files failed to download, they have been ignored, or old ones used instead. How do I fix this? Also can't seem to get the choppiness out of youtube videos. Appreciate your help. (Distributions)
