[Bug 2004077] [NEW] closing the OEM-config window instead of completing the setup removes oem user, uninstalls oem-config* and locks user out

[Hugo Venhorst]

Public bug reported:

After setting up an OEM install (vanilla Kubuntu 22.04) with the
temporary oem user, i started "prepare for shipping to end user" and
rebooted.

I was presented with the setup dialogue. I did not want to set up right then, so i closed the setup window.
- what i expected to happen:
get a dialogue box asking me to [shut down the computer | restart the setup from the beginning | continue the setup.]
(or maybe just cancel the setup and shut down the computer without further warning)

- what actually happened:
without further warning or explanation the setup was aborted, and a dialogue box appeared, showing the process of oem-config and a host of related packages being uninstalled. (this would be the cleanup script that should run after setup is COMPLETED?)

then the computer rebooted into a login screen with the user "oem"
preset. logging in with oem's password fails. I suspect the oem user has
been removed too, leaving the computer with no user account available.

Right now it is REALLY EASY for an end user to "break the computer", locking themselves out before they even get to use it!
Some fail-safe should be in place that either prevents the dialogue from being closed until setup is completed, or allows the setup to be aborted and the computer shut down for a later day.
