Hi Kaj,

Thanks for this. Yes, my wheels fail now, but doesn't seem to be an issue.
I think Ubuntu 16.04.5 LTS has some python updates, which cause this
issues. I guess as long as we keep track then this is fine.

Creating firmware and installs that work for everyone does come with its
issues.

Well spotted.

Kind regards,

Adam
