Error starting smart-proxy after install of remote execution ssh

Support

Problem: foreman-proxy (smart-proxy) will not start after install of ruby-smart-proxy-remote-execution-ssh with “uninitialized constant Dynflow (NameError)”. Note, I have installed an older package for ruby-concurrency to resolve Concurrent::Edge::Future issues.

Expected outcome: smart-proxy should start

This is definitely related to an early post, but it seems like the remote execution ssh smart-proxy plugin is a key bit.

Installing the ruby-smart-proxy-remote-execution-ssh package starts the problem, purging the package allows smart-poxy to start running again.

@corvar Note, I have installed an older package for ruby-concurrency to resolve Concurrent::Edge::Future issues.

With this “hack”, did remote execution work on this version of the foreman that you inform?

I have foreman 2.0 nightly and the same bug still happens.

The ruby-concurrency package install allows Foreman in general to run, but does NOT fix the remote execution ssh DynFlow error.

As an experiment, I spun up a CentOS 7 instance and installed Foreman on it. The remote execution ssh stuff seems to work on there.

A big difference between CentOS and Debian is that there is a process on CentOS:
ruby /usr/bin/smart_proxy_dynflow_core -d -p /var/run/foreman-proxy/smart_proxy_dynflow_core.pid

that has no equivalent on Debian.

Trying to execute that manually gives:

ruby /usr/bin/smart_proxy_dynflow_core -d -p /var/run/foreman-proxy/smart_proxy_dynflow_core.pid
