reg_linux_diskfull_installation_flat fails on ubuntu-22-ppc64le-devel and ubuntu-24-ppc64le-devel in build #121 of xcat-core-devel-ubuntu-cd. The node answers ping but the case ends on "root@xcat25-cn: Permission denied (publickey,password)" and the node status never leaves powering-on. The serial console shows why: the Subiquity installer starts, runs the early-commands, errors, tars /var/log/installer to port 8080 and reboots. Nine cycles in 75 minutes. The installed system never exists, so the address belongs to the live installer and it refuses the root key. Two causes, both POWER-only. mkinstall picks pre.ubuntu.subiquity, then overwrites that choice with pre.ubuntu.ppc64 for every ppc64 node. That script writes a partman recipe; the early-commands append it to /autoinstall.yaml, which Subiquity then cannot parse. pre.ubuntu.subiquity has a UEFI branch and a BIOS branch and nothing else, so a ppc64el node takes the BIOS branch and is given a bios_grub partition. POWER firmware boots from a PReP partition. debian_install_prescript.t drives the script choice, which mkinstall keeps inline, so it bails out. ubuntu_subiquity_storage.t gains a PReP case; its extracted block asks uname for the machine architecture, which the block does not do yet.

# Ubuntu has two installers and two pre-install scripts that are not interchangeable.
|
|
# pre.ubuntu.subiquity writes a curtin "storage:" document that the autoinstall
|
|
# early-commands append to /autoinstall.yaml. pre.ubuntu.ppc64 writes a partman recipe
|
|
# for the debian-installer, which is not YAML at all.
|
|

|
|
# mkinstall chose the subiquity script, then overwrote that choice for every ppc64
|
|
# node. A ppc64el 24.04 install therefore appended a partman recipe to its
|
|
# autoinstall.yaml, Subiquity failed on the malformed document, the error-commands
|
|
# tarred /var/log/installer and the node rebooted into the installer again -- nine
|

# case reg_linux_diskfull_installation_flat. The node answered ping from the live

# The ppc64 script belongs to the debian-installer path only.
