Comment 17 for bug 1990196

Oliver, per #15 I'd like to get this in place for 22.04 LTS production systems. If it's simple enough, can you point us on how to disable the Next and Back buttons on the last slide so we could at least patch it? We have done some work, but a bit of experienced direction would certainly be welcome, and we would of course report back here how well things may have worked.
