Public bug reported:

cloud-init version: 22.4
source: https://launchpad.net/cloud-init/trunk/22.4/+download/cloud-init-22.4.tar.gz
target platform: Rocky Linux 9, aarch64
hypervisor: Parallels 18
error output included at the bottom
--


Have successfully used this same process to build cloud-init during the packer image creation on Rocky (CentOS) 8 for x86 vbox and AMIs for a couple of years, and Rocky 7 before that. Obviously this was done on x86 hardware.

None of this might matter, but for the sake of transparency - I'm now
trying to build a Rocky 9 Parallels VM on an M1 mac (so aarch64), as
above, using packer. I can't compare to Rocky 8 arm because Parallels
won't boot a Rocky 8 arm iso, and virtualbox won't boot much of anything
on arm.

cloud-init appears to build (python3 setup.py build) fine, but is
crashing during the install phase, trying to do something with a
template.

I don't think I'm doing anything special. The provisioner script[1] that
packer is running to build/install cloud-init is pretty simple.

As to the python error specifically, I see two references to a var named
'u' in cloud-final.service.tmpl:

> ExecStartPost=/bin/sh -c 'u=NetworkManager.service; \
> out=$(systemctl show --property=SubState $u) || exit; \
> [ "$out" = "SubState=running" ] || exit 0; \
> systemctl reload-or-try-restart $u'

but I'm still trying to figure out what the replacer() method is doing
when it tries to return and hits the KeyError.
