Thanks for taking the time to report this bug and helping to make Ubuntu better.
It looks like the error you have experienced is related to a conflict between the packaged installation of puppet and a custom manual installation of puppet you have in /usr/local/lib/site_ruby/1.8/puppet. Thus this problem appears to be on your system and not a bug in Ubuntu. Accordingly I am marking this bug as Invalid in Ubuntu. If I am mistaken, please do explain and change the status back to New. ** Changed in: puppet (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to puppet in Ubuntu. https://bugs.launchpad.net/bugs/999082 Title: package puppetmaster 0.25.4-2ubuntu6.7 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/puppet/+bug/999082/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
