Hi, I had the same problem with cloud-init and chef.
Some package installation failed with code 100 (Dpkg sub-process failed). I manage to fix it by installing chef and running chef-client manually in the cloud-config : #cloud-config output: { all: '| tee -a /var/log/cloud-init-output.log' } packages: - chef chef: install_type: packages server_url: http://xxxxxxx:4000 validation_name: chef-validator validation_key: | -----BEGIN RSA PRIVATE KEY----- xxxxxxx -----END RSA PRIVATE KEY----- run_list: - role[front] runcmd: - [chef-client] I also have a problem during postfix package installation that become interactive when installed by chef through cloud-init. I tested with Ubuntu 12.04 and 12.10 on Amazon EC2. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to cloud-init in Ubuntu. https://bugs.launchpad.net/bugs/961142 Title: chef 0.10: package installation: returned 100, expected 0 To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/961142/+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
