python on a cloud server

[IMuriel]

I have had several Flask app running on Digitalocean.
For setup i have followed this How To Serve Flask Applications with Gunicorn and Nginx on Ubuntu 16.04.
Today i would have chosen How To Serve Flask Applications with Gunicorn and Nginx on Ubuntu 18.04.
Then use newer Python 3.6 --> that also has virtual environment build in(no install).
It also easier if has a GitHub/BitCucket repo with content of Flask app.
Then is git clone url_to_repo to get all files to DO.

thanks it is solved now, i had to destroy my dolpet and install all agian, and now its working
