Dear Daniel,
thanks for your reply. I tried variations. In the end I started from a 
blank/unmodified ubuntu LTE 18 VM.
I copied only your bootstrap (per instructions) executed it, but still  
hit this issue in the end.
regards

    Hi there,

      Sorry for being late with the response. You probably having an
    issue with the versioning of P4C. We are using an older version of
    it (the exact version info can be found in bootstrap-t4p4s.sh, line 7)

    Best,
      Daniel Lesko
