Ubuntu 12.04 Precise Preseed Templates

Support
1

Does anyone here have a set of working Precise templates they'd be willing
to share? I'm working through the process of creating a set, but I'd hate
to repeat existing work if it's not necessary.

The default Preseed{, PXELinux, Finish} templates worked for me in
Ubuntu 12.04, last time I tried it (a month or so back). What sort of
problems are you having?

Cheers,
Greg

Our Ubuntu 12.04 provision templates for preseed and PXE can be found here:

https://gist.github.com/2931362 (preseed)
https://gist.github.com/2931367 (PXE)

I had to play around quite a while before I found a combination of
parameter names and values for locales, keyboard layouts, languages,
etc. that worked. Some have to be set at PXE level, some in the preseed
file. There may be some redundancy there, but this is what worked for
us. Also be mindful of parameters that are specific to our Foreman
installation and infrastructure (such as root password, proxy/cacher, etc).

Basically that I have to manually do the entire installation. Though now
that you say it works, I'm thinking there's something else wrong.

And sure enough, a wget http://foreman/unattended/provision from the
installing server gives me a file with "Failed to clean any old
certificates or add the autosign entry. Terminating the build!"

So I'll fix that and see what's up.

Sounds like you might have the classic smart-proxy-sudo problem, where
a spoof-render of the template works, but wget-ing it on the client
fails. Ensure your proxy user can run "sudo puppetca" and such variants.

You are mostly correct. Spoof rendering does give me the correct file.
However, the proxy logs indicate there's no permissions to modify the
autosign.conf file, and there wasn't. I didn't realize puppet resets the
mode on that file when it runs, so I set the appropriate configs in the
puppet.conf file. I'm trying it out now.

Looks like that fixed my issue. It's picking up the templates and
processing them. I've got my next problem, though. It gave me a "Cannot
find root partition" or something or another. So my partitioning is wrong.
I used the "Ubuntu custom LVM" partition snippet but changes sda to vda
since I'm on KVM. I'm trying the "Ubuntu default" template now to see how
it goes.

Andreas, thanks for the templates.

I have added another Gist containing our all-LVM partition table for
KVM-based VMs (usually on a 10GB LV that is seen as /dev/vda in the VM):

Of course it doesn't work with real servers but since you are on KVM it
may be of use to you.
