pip install fails

[tobyaharris]

Tests on stable and development this morning fail at docker compose build.

 => ERROR [web 4/7] RUN pip install --upgrade pip && pip install -r requirements.txt                                                                                                                                                     0.4s

Perhaps the requirements versioning issue is relevant

[tobyaharris]

In quick testing none of the below fix this issue:

• Removing the unsecured dependency (openpyxl) ,
• Removing the dockerfile command to upgrade pip (reducing RUN pip install --upgrade pip && pip install -r requirements.txt to RUN pip install -r requirements.txt)
• specifing pip3 (changing said dockerfile line to RUN pip3 install -r requirements.txt. With that done, this line is the same as in Temperature dockerfile which works reliably, including on the same test pi (5) this morning.

It's because the dockerfile specifies arm32 (bit), I'm working on a 64bit system. I propose using the base image python:3.8 which will adapt to the hardware used.
