Felipe,Perhaps you can answer a question for me, I am in a similar boat as you with having to continue to support Lenny after EOL. I am trying to install puppet but I have an unmet dependency of libaugeas0. It appears that only version 0.2.2-1 is in the backports repository on archive.debian.org, and puppet from apt.puppetlabs.com requires version 0.6.0. What did you have to do to get this dependency met?Thanks for your help,Christian
