The Update Manager is giving me a problem. Each time I hit the Check for updates button, I get the following error:

W:Failed to fetch http://ppa.launchpad.net/weather-indicator-team/pp/ubuntu/dists/natty/main/source/Sources  404  Not Found
W:Failed to fetch http://ppa.launchpad.net/weather-indicator-team/pp/ubuntu/dists/natty/main/binary-i386/Packages  404  Not Found
E:Some index files failed to download. They have been ignored, or old ones used instead.

I re-install the Update Manager and then it works properly, the same issue was with the Software Center I did the same and it worked. Any help?

There is a typo in the PPA location ('pp' instead of 'ppa').

To fix this:

  • Press Alt + F2 and type gksu software-properties-gtk (press Enter)
  • After typing in your password, go to the Other Software tab and find the two entries that correspond to the error you posted.

    enter image description here

    [Just an example of how the GUI should look like, I don't have that PPA installed.]

  • Select each item, click on the Edit... button and fix the typo. The address should be


    for both entries.

Close and try the Update Manager again.

  • Open a gnome-terminal and type the following: sudo apt-add-repository ppa:weather-indicator-team/ppa. This should take care of authenticating the PPA. – htorque Sep 23 '11 at 16:35
