errors upgrading to saltstack v2020.42.1

I'm getting error upgrading to the latest saltstack v2020.42.1

the errors triggers after:

>> Running: ssh
Update returned exit code not zero
Error: Update returned exit code not zero
    at ChildProcess.<anonymous> (/snapshot/remnux-cli/remnux-cli.js:562:23)

    at Process.ChildProcess._handle.onexit (internal/child_process.js:286:5)

Buy by looking into it seem possibly related to this:

Hi @davidep , This is due to a recent update of r2pipe where they've removed all support for Python 2, and changed their build to support only Python 3.
I'm submitting the pull request to fix this now, but in the meantime, you can run the following to install:
sudo python3 -m pip install r2pipe

Cheers

Thanks for fixing this, @digitalsleuth! I just signed and issue a new release to incorporate your change.

@davidep, you should be good to proceed now. You can run remnux upgrade to finish the installation.
