How to install puppet devel from apt.puppetlabs.com?

Question

According to the README at apt.puppetlabs.com the repo is added by

wget http://apt.puppetlabs.com/puppetlabs-release-precise.deb
dpkg -i puppetlabs-release-precise.deb

but I only see the stable 2.7 version when I afterwards search in aptitude.

Even if I install release-unstable, I still only see the 2.7 version.

The devel version is listed in the Packages file.

Package: puppet
Version: 3.0.0-0.1rc3puppetlabs1
Architecture: all
Maintainer: Puppet Labs <info@puppetlabs.com>
Installed-Size: 492
Depends: puppet-common (= 3.0.0-0.1rc3puppetlabs1), ruby1.8
Recommends: rdoc
Suggests: puppet-el, vim-puppet
Section: admin
Priority: optional

So I suppose it is possible?

How to install puppet 3.0 rc3 on Ubuntu 12.04 from apt.puppetlabs.com ?

Answer 1

Looks like they have a /devel branch in their sources, as opposed to the /main that systems will typically use.

I presume their "setup" package creates a file in /etc/apt/sources.list.d/? You'll want to modify the source line(s) in that file - where it says main at the end of the line, you'll want to replace that with devel. Run an apt-get update and the 3.0rc3 packages should be recognized as current.

Just to clarify on unstable: what that refers to is the unstable release of Debian, not necessarily unstable puppet packages. What you're probably getting there is stable packages for an unstable OS.
