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 themeĀ·
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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1727908 Title: Software & Updates application does not permit changes on the "Other Software" tab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1727908/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
