Chef kitchen stopped working all of the sudden with "Could not find 'net-scp'" (Ubuntu 17.10)

Question

I was working on a project, and suddenly, any invocation to anything Ruby seems stopped working. All of them report missing dependencies.

I was uninstalling unrelated C/C++ -dev libraries before that, could be the cause because I didn't do anything else I would suspect.

I have tried reinstalling chefdk.deb (downloaded), I did sudo gem update --system which changed (looks like improved) the stack trace, but the error is still the same:

What should I do?

Can you share your gem list, you can check why it's looking for lower version of gem — Bijendra, Feb 06 '18 at 05:17
How do I list them? WRT version, that's buried somewhere deep inside kitchen's source scripts. — Ondra Žižka, Feb 06 '18 at 15:00

Ok so after sleeping well, I realized it is telling me it just can't find some library. So I started installing them, starting with sudo gem install net-scp.

I'm not sure though why they got uninstalled and why chef didn't install them with it's package.

Minor note, you aren’t using our packages. We do include it in the ChefDK packages, which we also recommend you use. — coderanger, Feb 06 '18 at 17:58
@coderanger Maybe I am not, I am only using `gem` for Chef, and while making things work, I could have used some nonstandard packages. What's the current recommended way for Ubuntu 17.10? — Ondra Žižka, Mar 09 '18 at 12:20
