and it works
My CF at RaspberryPi 3 with Stretch crashed :-(.
And it was not possible to reinstall Octoprint the normal way. Actual Octoprint version need Python 3.6+ and older Octoprint versions had fatal problems like need of unavailable Python Setuptool versions etc. For Stretch there is Python 2.7 and 3.5 available only.
Because of performance and some other software it is not realy possible to me to work with actual RaspiOS. I've to setup it by hand. There is also a milling machine and some other equipment driven by the Pi.
But its possible to go around and make Python 3.6+ running ahead Stretch. And so making the environment propper for actual Octoprint.
A guide from Switzerland figgered out, how to do it and he published it by
It's not for beginners but more for professionals! One has really to know, what he is doing.
Python 3.6.5 (what he used) does not work. There are some unit test and certification problems.
But Python 3.6.7 is good. Of course it needs some hours. The poor little Pi had to do much work to build Python from source. But at the end it had been successful.
And now the printer can be served by Octoprint again.
This as hint for some with same problem.
