Software and Updates /Other Software greys out when clicking on "Canonical Partners"

[René Lender]

"Other Software" only works after having clicked on "Ubuntu Software", "Updates", etc and changing some settings on those pages.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:
* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

[René Lender (rene-lender)]

Yes, the bug is reproducible when I run "Gnome on Xorg".
Running Gnome on Wayland this bug does not happen.

Please follow these steps (Xorg-session):

1. Open "Software and Updates"
2. Klick "Other Software"
3. Klick "Canonical Partners"
4. Instead of being asked for the password nothing happens. Toggles and text are greyed out.

I saw this error message in the terminal from which I launched software-properties:

 $ software-properties-gtk
ERROR:root:Authentication canceled, changes have not been saved

[enolive (enolive)]

encountered it after an update to 17.10 as well.
My workaround for now is to start software-properties-gtk using gksu

Also happening on Ubuntu 18.04
