Further to comment #4, this bug report should also be extended to cover Kubuntu, Lubuntu, Xubuntu etc. which also won't include gnome-control- center in a default installation.
If anyone really needs Livepatch then the work-around, as suggested by Bill and confirmed by me, of installing Livepatch from the command line will work. In the case of Xubuntu you even get an icon in the top bar to confirm that Livepatch is enabled and running. ** Tags added: kubuntu lubuntu xubuntu -- 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/1844426 Title: Impossible to set up Livepatch on Ubuntu MATE Status in Ubuntu MATE: Confirmed Status in software-properties package in Ubuntu: Confirmed Bug description: In Ubuntu MATEE 18.04, in the Software Properties window (available from Software Boutique > Preferences > Show Software Sources > Manage Repositories, among other places), there is a Livepatch tab. This tab says "To use Livepatch, you need to sign in" and provides a "Sign In..." button. This button launches an empty version of gnome-control-center with no icons in it. If one is technically adept, it is possible to do what (I think) that button is trying to do by launching g-c-c directly in a terminal and overriding the desktop, thus: env XDG_CURRENT_DESKTOP=GNOME gnome-control-center online-accounts This online accounts window permits attempting to add an Ubuntu One account. However, when one tries, a window pops up with a place to add one's Ubuntu One username and password, but the window has no Submit button; there is no way to actually initiate sign in.
