I was able to work around this by using <TAB> to select a source and <SPACEBAR> to activate the check box. Now I can check/uncheck at will and have no errors.
I noticed yesterday when I encountered the bug it didn't prompt me for password when I made a selection, but today it does (whether I check or uncheck the box) every time I open that dialog. Hope this information helps. If I figure out more details I'll post them as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/828850 Title: software-properties-gtk crashed with DBusException in call_blocking(): com.ubuntu.SoftwareProperties.PermissionDeniedByPolicy: com.ubuntu.softwareproperties.applychanges To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/828850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
