New tbot requires python 3.6+.  I use a lot of features introduced
in 3.6 which means that I can't support older versions.

Yes, this fails because type-annotations (what you are seeing in that
error message) were introduced in python 3.6 while you try to run the
code on 3.5.  That won't be possible, I'm afraid ...

I am not quite sure what you are trying to do.  Do you intend to run
tbot *on* the BBB?  Is your plan to use the BBB as a kind of CI runner?
