Is my Ubuntu 10.10 corrupt?

[msinfo]

Hi,

Today I was trying to install few, programs, but because of error message - "Requires installation of untrusted packages", I could not install any.This happened for python idle3, when i tried sudo apt-get install idle, it went perfectly with message, that some packages couldn't be installed. When I tried to launch it, it failed stating such program is not installed.

This happened with other programs too.
When I try to update my Ubuntu, to latest release, I saw error message - "Failed to download repository information". I saw following in details.

:Failed to fetch http://extras.ubuntu.com/ubuntu/dist...86/Packages.gz 404 Not Found
, W:Failed to fetch http://security.ubuntu.com/ubuntu/di...86/Packages.gz 404 Not Found [IP: 91.189.92.201 80]
, W:Failed to fetch http://security.ubuntu.com/ubuntu/di...86/Packages.gz 404 Not Found [IP: 91.189.92.201 80]

and many more.

Note: Also, when this question gets solved, how do I mark it as solved? Because I could not found any option for doing that, in my last two question, because of changes occurring in interface of forums.

Kindly guide me.

Thanking you.

10.10 reached EOL a year ago. Time to move on

So how do I update my system now, without re-installing Ubuntu.

Really should do a fresh install in this case as you will need to upgrade to 11.04 next and thats EOL, then 11.10, then 12.04.

Thanks ibjsb4 for info.
Currently I am upgrading to 11.04, using help from Help file topic : How can I upgrade to the latest version of Ubuntu?
and command update-manager -c -d. It's under process.
But can I know, what makes it to fail install python idle3 via Ubuntu Software Centre or command line. This not only happens with idle but with others software's too which I want to install.

Post back when your 11.04 upgrade is complete, let us know how it went.

How can I upgrade to the latest version of Ubuntu?

Next is 11.10 and then your one step away from 12o4 LTS, supported till 2017

Really, you must do a Clean install of the latest version available, ie 12.04 or 13.04. It will save you both time and other possible headaches...

Doing a clean install really is a better idea than going up the versions, one-by-one, especially if your version has reached EOL. This will result in a tangled mess of repositories and other packages, so it's worth the trouble of burning a disc over migraines.

You can't go up to 11.04 either, it's also well and truly out of support.

A clean install is now the only way, you've left it too long to do an in-place upgrade.

These days you can do a clean install while retaining your home folder (even if it's in the same partition as /). It's really very easy.

Really? i thought you had to format it oh well.

You really should just do a clean install though, upgrades are never pretty
