Foreman » Packaging

I'm setting up a puppet + foreman + foreman-proxy server using the theforeman-* puppet modules, and got stuck when trying to install ruby-smart-proxy-remote-execution-ssh. Seems like the Ubuntu Xenial repo dependencies are broken for latest versions available. I've figured out a workaround to install some older versions of the packages, however at the moment the Puppet modules does not allow specifying the individual versions of plugins.

To check if this is not an issue with how I've setup the box, I've tried it out in a fresh OS install as well, the repos in-fact seems to have missing dependencies.

Steps to reproduce¶

On a fresh Ubuntu Xenial install,
- Added the foreman repo

deb http://deb.theforeman.org/ xenial 1.15
deb http://deb.theforeman.org/ plugins 1.15

- Updated package list

sudo apt-get update

- Installed foreman proxy

sudo apt-get install foreman-proxy

- Tried installing ruby-smart-proxy-remote-execution-ssh

apt-get install ruby-smart-proxy-remote-execution-ssh

Investigation notes¶

Based on the packages available in the 1.15 repos, this is what I found so far,

ruby-smart-proxy-remote-execution-ssh (latest = 0.1.6-1)
  |
  |-- requires
        |
        |-- ruby-foreman-remote-execution-core (>= 1.0.6) -- MISSING - http://deb.theforeman.org/dists/xenial/1.15/binary-amd64/Packages only has up to 1.0.5-1
        |
        |-- ruby-smart-proxy-dynflow (>= 0.1.0, < 0.2.0) (latest = 0.1.8-1)
              |
              |-- requires
                    |
                    |-- ruby-smart-proxy-dynflow-core (>= 0.1.5) (latest = 0.1.8-1)
                         |
                         |-- requires
                               |
                               |-- ruby-foreman-tasks-core (>= 0.1.7) -- MISSING - http://deb.theforeman.org/dists/xenial/1.15/binary-amd64/Packages only has up to 0.1.4-1

Workaround¶

You can get around this by manually installing specific versions without relying upon the latest available in the repo. The following combination worked.

sudo apt-get install ruby-foreman-tasks-core                     # installs 0.1.4-1
sudo apt-get install ruby-smart-proxy-dynflow-core=0.1.6-1
sudo apt-get install ruby-foreman-remote-execution-core          # installs 1.0.5-1
sudo apt-get install ruby-smart-proxy-remote-execution-ssh=0.1.5-1
