What are 404 errors

The 404 or Not Found error message is a HTTP standard response code indicating that the client was able to communicate with the server, but the server could not find what was requested.
The web site hosting server will typically generate "404 - Page Not Found" web page, when users attempts to follow a broken or dead link.

Why are we facing 404 errors

Ubuntu follows the approach of two different release cycles:
Normal Ubuntu releases are supported for 9 months. LTS releases are supported for 5 years.
Past releases may have different support schedules (for example, normal releases (before 13.04) used to be supported for 18 months, while LTS releases (before 12.04) used to be supported for 3 years on the desktop and 5 years on the server).
EOL: Once the support period for a particular release is over; they are called End Of Life (EOL) and all the updates and package repositories for that Release are transferred to a different server which results in 404 errors while running sudo apt-get update. You can confirm if your release has become EOL by going to this page. If your Ubuntu release is mentioned under "End Of Life (EOL)" Table, then the release is no longer supported and you should try to upgrade to a newer supported release. However, if you wish to continue using this unsupported release, you would have to make necessary modifications in /etc/apt/sources.list to point to the old-releases server of Ubuntu.

Steps to make necessary modifications

  1. Open your Terminal:
    • Press Ctrl + Alt + T; OR
    • If you have Gnome: ApplicationsAccessoriesTerminal; OR
    • If you have Unity: press Super (the key between Left Ctrl and Left Alt) and query for Terminal.
  2. Run the following command:
    gksudo gedit /etc/apt/sources.list
    input your user password and press Enter.
  3. Find the first line which doesn't start with #. Suppose you are running Karmic Koala (Ubuntu 9.10): it should be like the following line:
    deb <siteurl> karmic main restricted
    where, <siteurl> is your preferred server - in your case (for example).
  4. Press Ctrl + H to replace your <siteurl> with
    • Search for: ie; <siteurl>
    • Replace with: and
    • Press Replace All
  5. Once again:
    • Search for: (this exact url for all the Ubuntu Releases — whatever be the present server that you are using)
    • Replace with:
    • Press Replace All
  6. Save your file and exit Gedit.
  7. Run the following command:
    sudo apt-get update
There you go. No 404 Errors this time. You can now install all the available packages for your Ubuntu Release. You can also run sudo apt-get dist-upgrade to install any Security/Bug-fix updates which have not yet been installed but you won't get any further Security/Bug-fix updates from Ubuntu.
