How to install software or upgrade from old unsupported release?

I am using ubuntu 10.10, here i am not able install any paint tool. If i try to install some tool, it will show below message in a dialog box.

 Requires installation of untrusted packages

 The action would require the installation of packages from not
 authenticated sources.

Please suggest some paint tool along with installation steps.

Also i have tried $ sudo apt-get update but it is showing like below


Err maverick-updates/multiverse i386 Packages 404 Not Found [IP: 80]

Ubuntu 10.10 is End-of-Life and the Extras repository does not have any software for this version of Ubuntu anymore. Upgrade to a newer stable release of Ubuntu. – gertvdijk Jan 30 '13 at 22:48

Try removing any PPAs you added, and switching from the Indian mirrors to another mirror using the Software Sources tool.

Exactly, i don't know what all PPAs i need to remove? – Shruthi R Jan 30 '13 at 10:16
1) The error is not about PPAs. 2) Mirror says: 404 correctly because it's EOL'd – gertvdijk Jan 31 '13 at 0:57
EOL means End-Of-Life, that release of Ubuntu is no longer supported and the mirrors don't contain packages for it any more. – Flimm Jan 31 '13 at 10:27
