Cannot edit Software Sources after upgrading from 12.10 to 13.04

  • 772

I go to System Settings -> Software sources. I see there many Software sources with the comment "disabled on upgrade to raring". When I click on the check-button or select ppa name to edit/delete that source nothing happens. This behaviour only occurs with sources inherited from 12.10. Sources added after upgrade can be removed correctly.

What should I do?

upgrade

  1. You don't have to click on check buttons just click on the ppa and the click on remove button below.
