Installation in OEM mode broken on bionic

As advised by xnox I have retried the installation with adding apt-setup/proposed=true.

The result was identical - after rebooting to perform the oem configuration the boot process stucks.

Attaching installer logs.

So this is strange, I can reproduce the bug, but an oem install in UEFI mode works, and a normal install in BIOS mode works, only an oem install in BIOS mode doesn't work. Which doesn't make any sense at all on the face of it.

Oh wait no it does boot, it just takes a very very long time. Dariusz, how long did you wait for it to boot?

Michael, I've just tried again today. I have up waiting after 60 minutes. How long does it take in your case?

FWIW I used a vm (kvm) for testing.

Oh, I misread the bug report, I thought that the system wasn't booting at all :(

The good news is that I can reproduce your issue now I understand what it actually is! The bad news is that I don't really know what to do about it. <email address hidden> is being prevented from running by ubiquity.service via systemd's Conflicts= mechanism. I don't really know why though, perhaps it can simply be removed -- I also don't understand terribly well how all of this stuff is supposed to work.

There is an easy workaround though, just switch to tty2 after booting.

So I think this patch (to ubiquity):

will fix the issue, it's a bit gross though.
