How can I fix a 404 Error using a PPA?

For some reason every time I try to update by terminal, synaptic, and update manager I get this error message and I cannot update all the data I need.

  • You've mentioned that you're upgrading to 11.04, but your log indicates that it's downloading 10.04. Can you edit to clarify which version you're running, and to which you're upgrading?

Using Update Manager click the "Settings" button. This will open your Software Sources windows:

  1. Untick the "CD-ROM" option - in my case it is "Ubuntu 10.10"
  2. Go through the list and untick all your PPAs
  3. Then click close
  4. Check that you can now update successfully.

If you still cannot update then change your download mirror to another server: enter image description here][2
