To Reproduce

You can exec into a pod and try to clone a repository and will get an error regarding ssh package not being installed

Describe the bug

Since yesterday at around 14h Paris time, our ci jobs started to fail with error Error: Unable to locate executable file: ssh. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also check the file mode to verify the file is executable.

Describe the expected behavior

Expected behavior : be able to clone a git repository (with action/checkout for example)

Additional Context

Our team rebuild the docker image by adding the ssh client again Example bellow (i do not recommend using latest)

FROM summerwind/actions-runner:latest

USER root

RUN apt-get update -y \
  && apt-get install openssh-client -y \
  && rm -rf /var/lib/apt/lists/*


USER runner

My question is : did the summerwind contributors removed the ssh clients ? If yes, where could we have been informed of the change ?

I'm posting this because others might run into the same issue and i wanted to offer a quick solution, i hope that's okay !

Looks like the latest tag in summerwind/actions-runner points to version that is missing ssh. Using the exact version tag (e.g. v2.329.0-ubuntu-20.04) seems to resolve the issue.

It seems previous latest release was based on ubuntu20.04 image as I have similar issue but with ping and nslookup.

There is significantly more binaries in /usr/bin/ in 20.04 compared to 22.04 and recently added 24.04:

I have noticed that make is also not available. I guess you should rebuild latest with all that was installed before. I think that maybe the latest ubuntu package repos changes has something to do with this

Looks like this PR: https://github.com/actions/actions-runner-controller/pull/4061 add the missing binaries ?

[valeriy-soloviov-wd]

Looks like this PR: #4061 add the missing binaries ?
