More details:

If I disable apparmor on the host machine by adding apparmor=0 to the linux ... boot commands in Ubuntu's /boot/grub/grub.cfg file, the Plesk build/install succeeds. I will consider this to be a work-around. Is there a way to run Plesk with apparmor?

[sibprogrammer]

Unfortunately there are problems with Plesk installer and AppArmor both for 12.0 and 12.5 version. I've added information about AppArmor issue to the list of known issues (README.md) Thank you.

[sibprogrammer]

Issue has been fixed in scope of Plesk Onyx (latest image).
