Install on Debian Bullseye fails due to python2 requirements
Bug description: Using most recent Raspbian Version 11 (Bullseye) the install fails during the line 56: https://github.com/openaps/oref0/blob/acb0150021e7bf284b6741a9510076a13f690747/bin/openaps-install.sh#L56 Throwing the error: E: Package 'python pip' has no installation candidate Due to python2 being removed on this version of Raspbian.
To Reproduce Steps to reproduce the behavior:
- Flash bullseye to new SD card
- Run usual installation process
- See error
Expected behavior Expected installation to complete or at least get through python installations
Setup Information (please complete the following information):
- Pump type: Medtronic 722
- CGM type: Libre with xDrip+
- Rig type: Pi Zero 2 running Raspbian Bullseye
- oref0 version: 0.62 master
Additional context Is python2 required for installation? Or would it be possible just by updating the installation code to python3-pip?
Thanks!
Python2 is required for installation because most of the python in oref0 is python2 Python3-pip is installed later on (during oref0-setup) but this is of no use because we need python2 versions of the modules.
Prior to Bullseye, Debian did the 'smart' thing and assumed that references to 'python' meant Python 2 (meaning that if you want to use Python3 you had to #!/usr/bin/python3 (or similar).
Bullseye turned this on it's head and made Py3 the default, while removing py2 pip from the distro.
The 'fix' is 2-fold: install the python-is-python2 and python-dev-is-python2 packages, and manually install pip2 from pypa with curl.
A further change that is needed, is to add awareness of aarch64 to oref0-setup's go install routines, because 64bit Bullseye for raspberry pi is now a thing.
Also, because the install routine uses openaps-install.sh from master even-if you are installing DEV branch, this has to be patched in both branches for it to work when installing DEV.
Patches submitted to address this - #1428 (master) and #1429 (dev)
