So we're dealing with some system which appears to be detected as something different than we're used to then. From what I can tell the partman-prep package would get installed if the subarchitecture is correctly detected as chrp_ibm or prep, etc.
AIUI this would come from archdetect. Could you please run the archdetect command in a terminal on the system, and tell us here what it reports? The result should be in the form 'ppc64el/subarchitecture', I somewhat expect that the subarchitecture on this system is reported as 'unknown'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1533587 Title: Ubuntu 14.04.04 installer does not list Prep Boot in Partition Settings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/partman-prep/+bug/1533587/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
