How can I fix a 404 Error using the Ubuntu archives?

I am having trouble downloading the Ubuntu repositories:

$ sudo apt-get update
...
Failed to fetch
http://archive.ubuntu.com/ubuntu/dists/maverick/main/binary-amd64/Packages.gz
404  Not Found

I can connect to the server fine:

# ping archive.ubuntu.com

Here is my sources.list:

deb http://archive.ubuntu.com/ubuntu maverick main restricted universe
deb http://archive.ubuntu.com/ubuntu maverick-updates main restricted universe
deb http://archive.ubuntu.com/ubuntu maverick-security main restricted universe

and system details:

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 10.10
Release:    10.10
Codename:   maverick

Any ideas?

As a release gets old (especially if it is not a LTS release), it becomes no longer hosted at archive.ubuntu.com. However, the repository is still hosted at

http://old-releases.ubuntu.com

So try changing your repository source to http://old-releases.ubuntu.com.
