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.

    The question and accepted answer is about raring and your answer is about bionic. Jun 11, 2018 at 1:52
  • @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.

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.

  • On second line I got : Error: 'deb extras.ubuntu.com/ubuntu' invalid

  • 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?

  • I've got the same, and I left them alone.
