I forgot to add something important: his error only happens after the upgrade of foreman_proxy_plugin_remote_execution_ssh

3

How did you perform the upgrade? If you say it happened after upgrade of foreman_proxy_plugin_remote_execution_ssh, what was the old version and what is the new one?

Thank you for your answer. I went from foreman 1.21.4 to foreman 1.22
For the upgrade

1 I changed the sources.list
deb http://deb.theforeman.org/ stretch 1.21 => deb http://deb.theforeman.org/ stretch 1.22
deb http://deb.theforeman.org/ plugins 1.21 => deb http://deb.theforeman.org/ plugins 1.22

2 apt-get update && apt-get upgrade -y && foreman-intaller

3 when launching foreman-installer, I had the error in the logs

module:ForemanTasksCore: uninitialized constant Dynflow (NameError)
....
foreman-proxy.service: Main process exited, code=exited, status=1/FAILURE
Failed to start Foreman Proxy.

to determine who was responsible for these errors, I made apt-get remove
when i uninstalled apt-ge autoremove ruby-foreman-remote-execution ruby-smart-proxy-remote-execution-ssh, and replayed foreman-installer, everything went well and the foreman-proxy started

to reproduce the bug, I launched the foreman-insaller -i and I activated the foreman_proxy_plugin_remote_execution_ssh (key 56)

But I need to run remote tasks with ssh

@1visible @aruzicka

The same error still happens on foreman nightly + debian 10.

I’m still stuck on version 1.21
can you help me ?
thank you

Also on Debian 10 with Foreman 1.24
