How to install software or upgrade from old unsupported release?
I have the Maverick release of Ubuntu 10.10 and the only release that is suggested to me is Natty 11.04. But the files cannot be retrieved from servers to install Natty because as you can see here, they don't exist anymore... http://extras.ubuntu.com/ubuntu/dists/. Ubuntu thus tells me I must have a connection problem because it cannot find files. (which is not the case).
Do you know if I can manually download, open and execute the files from another release (Oneiric for example)? Thanks a lot in advance,
Pauline
