I've been trying for days now to install Eclipse on Ubuntu 10.10 but it never works. if I double click on Eclipse icon, it does nothing. I've tried to change permission and applying methods I found but none of them works. Also Software Center is not downloading or installing anything.
It shows errors similar to this one:
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/maverick-backports/multiverse/binary-i386/Packages.gz 404 Not Found [IP: 91.189.92.202 80]
E: Some index files failed to download, they have been ignored, or old ones used instead.
OR
