Same problem with the KDE frontend (see the screenshot in attachment). See http://paste.ubuntu.com/597838/, there are two "natty-security", two "natty-proposed", two "natty-updates" with the same name and the same description, the only differences are the field "RepositoryType" (deb- src). software-properties uses aptsources which parses this file, then for each "Suite" it displays its name and its description with a checkbox => so we've duplicates options in the "updates" tab.
The "none" checkbox is due to a missing description for the Suite line 27. ** Attachment added: "screen1.png" https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/769364/+attachment/2084526/+files/screen1.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/769364 Title: Software-sources showing repeated options -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
