How to fix Ubuntu/Debian apt-get 404 Not Found Package Repository Errors (Saucy, Raring, Quantal, Oneiric, Natty…)

Ubuntu End of Life Package Repository

If you’re using a normal version of Ubuntu such as Saucy, Raring, Quantal, Oneiric, Natty, Maverick, etc, you may have already (and will eventually) start getting “Failed to fetch 404 Not Found” errors when trying to run  apt-get update , or even sometimes running apt-get install , but fear not, it is easy to fix, and here’s how…

Why am I getting this error?

Normal Ubuntu releases are supported for 9 months, whereas LTS (Long Term Support) releases are supported for 5 years.  Once support is up for the version of Ubuntu you are using the repository is moved to another server and will no longer be available on the standard location.

The most simple solution would be to upgrade to a newer version:

BUT, for some of us that isn’t an option right now, or maybe you don’t want to upgrade.  With a simple sed command you can update the  /etc/apt/sources.list file to use the new location for the old package repository.

How can I fix it without upgrading?

Run this command below on your server and it will replace all of the  and package repository URLs with

For Linux Mint, run this command as well:

You may also want to see if there are other files in  /etc/apt/sources.list.d/  that need to be updated, which can be done with a simple grep command:

Now update apt-get sources:

  • Wenya Wang

    Same question for undoing it. The dist-upgrade works great after editing the sources.list file. Yet after reboot, the connection to repository fails again..

    Thanks !

  • Thank you!

  • peliculiar

    WOW, that’s great, although I’ve broken the part of the sources that were still OK. I’m a Linux Mint Rebecca user. How can I undo that?

    • Matthew Rosov

      agreed – how do I undo these commands?

    I was reading this on one machine and doing the update on another. Took a while to figure out that | was a vertical bar rather than an L.

  • Marcos Carlevaro

    Thank you! Note: In my case, running on Amazon AWS, you need to edit sources.list to remove the reference to the amazon server, example: “us-east-1.ec2”.

    • Gery M

      did you find your solution, i am stuck no solution

  • richardwicks

    Wait, I have a question:

    This appears to happen if you neglect to update your linux box for some time. Is that true?

    I ask this because I am running a basically stock version of Linux Mint 17.2 which I just installed maybe a month ago on a virtual machine, and haven’t really paid attention to it on the VM.

    Is this why it happens? Because I think a LOT of people are running into this problem for that reason alone. I never use this machine.

  • AWC

    Excellent! Thank you for the useful tip. One would imagine that Linux Mint devs would roll out an update for aging distros to properly update the repositories.

  • panchodev

    Thanks for the info we the people around the world who cant afford new computer systems appreciate solutions to software issues with old but still useful hardware.

    Woo! Worked on Linux mint 14 nadia. Though the second listed sed command found no file, the first did the trick.

    Thanks. Linux Mint 15. I wasn’t able to install various packages lately. Now I can. I’m glad I found this page before trying the 99% other stuff on internet that doesn’t usually work. Good job.

    OH MY GOD! OH MY GOD! OH MY GOD! You are the greatest person on this planet. I love you so much.

    I’ve been throwing my head against a wall for the past hour and a half just trying to install openssh-server on Linux Mint. I had no idea the old sources were moved when a new LTS came out!!!! I cannot thank you enough, you ended my immense confusion (I tried so many other fixes, thinking I was behind a proxy, I had invalid sources, etc.) and solved my problem.

    Again, you are amazing.

  • Herbert Bothetele

    The command worked fine but I had to append the file name(sources.list) at the end.

    Thank you.

  • personface

    thank you for posting the practical solution.
    most answers on forums explicitly claim upgrade as the only option.
    you’re correct to point out that oftentimes, upgrade is no option at all.
    for instance, i can’t upgrade since my graphics hardware is no longer supported.
