No more media will be produced for Ubuntu MATE 23.04, so little can be done about that release.

Ubuntu MATE did not use the `subiquity` installer, using instead `ubiquity` which may or may not be used for subsequent releases (`ubiquity` being replaced by `ubuntu-desktop-installer` for 23.04 as default for Ubuntu Desktop, though not flavors).

Subiquity is used by Ubuntu Server ISOs.

I'll mark this incomplete; as `ubiquity` will continue to be used for Ubuntu MATE 22.04.3 and subsequent ISOs, but its undecided if anything else, and no more 23.04 ISOs will be produced. Thus any problems on install media of 23.04 CANNOT be corrected.

You could re-try this with mantic (23.10); as ubiquity is still used currently for Ubuntu MATE (https://cdimages.ubuntu.com/ubuntu-mate/daily-live/current/mantic-desktop-amd64.manifest) but no Ubuntu MATE ISO has used subiquity.

I just re-evaluated this for Ubuntu 23.10 and updated it at https://bugs.launchpad.net/ubuntu-desktop-installer/+bug/2025042

Oh: "subiquity" part, aka "ubiquity for servers" - https://github.com/canonical/subiquity. Thank you regarding the clarification of `subiquity` and `ubiquity`, but, can you please give me a bunch of references that I can read, so I can make improve my bug reports.

What I heard is that Ubuntu 23.?? is using subiquity and not ubiquity, is that wrong?

This bug is still valid for ubiquity, right? So why is it marked as incomplete? What is required to re-evaluate this issue for ubiquity?

I don't believe ubiquity does anything that interferes with the behavior of the 'Shut Down' button on the MATE menu. Reassigning to ubuntu-mate-meta.

Steve, you are right, I just re-evaluated this with Ubuntu MATE 22.04 and used `shutdown -h now` and a reboot was still forced.

Thank you!
