Comment 4 for bug 1754872

@Timur
I can't confirm this behavior on Ubuntu 18.04 LTS with MATE DE (installed from [mini.iso](http://archive.ubuntu.com/ubuntu/dists/bionic/main/installer-amd64/current/images/netboot/mini.iso) as `ubuntu-mate-desktop` package).
I do not have `gnome-control-center` executable in such system. I'll test official [beta-1](http://cdimage.ubuntu.com/ubuntu-mate/releases/18.04/beta-1/ubuntu-mate-18.04-beta1-desktop-amd64.iso) and report again.
