installing evok on debian bullseye - a bypass
In debian buster, there was still support for pip2 and python-ow, but in the latest debian version, in bullseye, this support is dropped. Therefore it is not possible to install evok on the latest release without some tricks.
I have been looking for a way around and below you find an ansible script that make this happen in an automated fashion.
When not versed in ansible, the things to do are:
- pull repo evok from git
- curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
- check pip2 --version
- replace in install-evok.sh everywhere pip install with pip2 install
- install nginx before with sudo apt-get install nginx
- add line to /etc/apt/sources.list --> deb http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
- sudo apt-get update
- sudo ./install-evok.sh
goodluck!

With the latest evok 2.4.20 release I could install it without any issues with latest bullseye 32 bit and 64 bit version.
Hello, as @PEPITO82 wrote, the latest releases are Debian 11 Bullseye compatible. We rework the install script and migrate 1Wire subsystem to onewire pip package instead of the python-ow Debian package that is no longer available.
