Sebastien, at present I can't confirm this on Xubuntu 18.04 but I still see a problem with Ubuntu 18.04 for which I have vanilla-gnome-desktop installed so using the Adwaita theme·
If I try to select or deselect anything on the "Other Software" tab I see the panel dim slightly as if the prompt for the admin password was going to appear but it doesn't. Just this tab is affected. But *sometimes* if I first select an item on another tab, cancel the password prompt and return to the "Other Software" tab then the password prompt does appear when selecting or deselecting an item. Unfortunately, the above is not reproducible every time and while testing before posting here (by repeatedly switching tabs and trying to select or deselect items) the application crashed and invited me to send a crash report. I see this problem when starting Software & Updates as a stand alone application and also through GNOME Software but not through synaptic as my password has already been entered. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to software-properties in Ubuntu. https://bugs.launchpad.net/bugs/1727908 Title: Software & Updates application does not permit changes on the "Other Software" tab Status in software-properties package in Ubuntu: Confirmed Bug description: On the "Other Software" tab, I am unable to select "Canonical Partners". Similarly, the other checkboxes on the "Other Software" can not be clicked. Clicking on a checkbox has no effect, and a dialog requesting the admin password is not presented. However, activating or deactivating checkboxes on other tabs causes an authorization dialog to be presented to the user.
