Open Stack

Hello:

I wanted to give the TripleO a try, so started follow our
installation guide for Ussuri, and eventually made it to
"openstack undercloud install". It fails with something like this:

Aug 28 10:10:53 undercloud puppet-user[48657]: Error: /Stage[main]/Ironic::Pxe/File[/var/lib/ironic/tftpboot/ipxe.efi]: Could not evaluate: Could not retrieve information from environment production source(s) file:/usr/share/ipxe/ipxe-x86_64.efi
Aug 27 20:05:42 undercloud puppet-user[37048]: Error: /Stage[main]/Ironic::Pxe/Ironic::Pxe::Tftpboot_file[pxelinux.0]/File[/var/lib/ironic/tftpboot/pxelinux.0]: Could not evaluate: Could not retrieve information from environment production source(s) file:/tftpboot/pxelinux.0

Does anyone have an idea what it wants?

I added a couple of packages on the host system that provided
the files mentioned in the message, but it made no difference.
Ussuri is conteinerized anyway.

Since I'm very new to this, I have no clue where to look at all.
The nearest task is a wrapper of some kind, so the install-undercloud.log
looks like this:

. . .

If anyone could tell roughly what is supposed to be going on here,
it would be great. I may be able figure out the rest.
