I can't update Ubuntu 2 months now

  • 772

So when running sudo apt-get update i get errors:

Err http://ppa.launchpad.net quantal/main amd64 Packages
  404  Not Found
Err http://ppa.launchpad.net quantal/main i386 Packages
  404  Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

Because of that update manager always popus up message that i should check my internet connection. So what do i do? How do i remove this packages?

Btw the skype problem started from the moment i tried installing skype from USC.. I ended up installing skype by deb file but having this problem from then...

Also my etc/apt/sourced.list.d doesn't have a skype file or a subfolder..

Ubuntu 12.10 here

12.10

    I recommend first to comment out or remove those 2 PPA which are not part the official repositories and are the ones giving you an error.

    First install ppa-purge which is in the proposed repositories in case you don't see it:

    enter image description here

    If you don't have the proposed repositories enabled, you will not be able to do it with the error you have right now, so for the moment you will need to do the following:

    1. Open the DASH and type sources, it should show you Software Sources. Open it and go to the Other Software tab. It should look something like the following image:

      enter image description here

    2. Start removing/disabling any PPA you do not need apart from the ones that gave you an error which were:

      http://archive.canonical.com/commercial-ppa-uploaders/skype/ubuntu/dists/quantal/main/binary-amd64/Packages

      http://archive.canonical.com/commercial-ppa-uploaders/skype/ubuntu/dists/quantal/main/binary-i386/Packages

      http://ppa.launchpad.net/cooperjona/stormcloud/ubuntu/dists/quantal/main/binary-amd64/Packages

      http://ppa.launchpad.net/cooperjona/stormcloud/ubuntu/dists/quantal/main/binary-i386/Packages

      If you click on any of this links you will get as 404 error which means the source moved to another planet (It is gone!!). So look for this in your Other Software tab and remove them. After that remember to activate the Proposed repository and simply close Software Sources.

    3. Now go to a terminal and: sudo apt-get update.

    It should work now, if not, look at the error message and remove any following PPA that gives you trouble.
