The bug is Ubuntu failing to display an authentication prompt. A potential solution to this is simply to run the software as root:
sudo software-properties-gtk
It's also possible (as @Abdel-Rahman notes) to edit the sources.list
file directly. The software-properties-gtk application does just edit that file, commenting or uncommenting the line as needed. Using add-apt-repository
will duplicate this line, and have no effect on the authentication bug: it's not actively harmful, but it's not a preferable solution.

The accepted solution works fine alternatively you can navigate to and edit sources.list file directly from terminal using
sudo nano /etc/apt/sources.list
find the line that says
#deb http://archive.canonical.com/ubuntu bionic partner
remove the comment and save(Ctrl+X), and you're done.

@WinEunuuchs2Unix that detail aside, editing the file directly is almost certainly the better solution than the accepted answer. The issue is that gnome-shell is failing to display an authentication prompt. – Kaia Leahy Dec 07 '18 at 08:16
Try this. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:
sudo add-apt-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner"
sudo add-apt-repository "deb http://extras.ubuntu.com/ubuntu raring main"
sudo apt-get update
Then go back to Software and Updates, and check to see if its OK
Note: in the second command replace raring with your Ubuntu version.

Works, but now in Software and Updates there are 2 Canonical Partner and 2 Independent, the original (on the top) is still unchecked, should I remove them? – Nur Jun 29 '13 at 19:42
