Test Case ======== 1. Follow the GNOME instructions at https://flatpak.org/setup/Debian 2. After restarting, open the GNOME Software app and install an app from Flathub. I suggest Chess Clock, which is a GNOME Circle app that is not yet packaged as a .deb for Debian 3. Open the (GNOME) Settings app. Navigate to System > Users. Unlock. 4. Click Add User. Fill in the name and user name. Make sure that Administrator is not selected. Finish adding the user. 5. Open the Parental Controls app. Unlock. 6. Click Restrict Applications. The Flatpak app (Chess Clock) should be in this list.
You'll likely need to log out and log back in after installing the updated malcontent packages. Thank you, Jeremy Bícha
