Calibre-Web officially desupports 32-bit ARM due to lack of Rust (like JupyterHub?)

[holta]

FYI:

• Installation on ARM32 device fails, error while building wheel for cryptography janeczku/calibre-web#2697

JupyterHub might do the same possibly?

• PR Til wheels / cryptography fixed: ansible-core 2.12.10+ PPA on 32-bit RasPiOS #3421
• PR Block iiab-install of JupyterHub & Calibre-Web on 32-bit OS's, til RasPiOS fixes Rust, wheels / cryptography #3422
• PR Closed Issue: revert to using pip for ansible on 32bit RasPiOS [& ongoing issues w/ wheels, cryptography, rust] #3459

32-bit RasPiOS might/possibly have Rust restored in coming weeks:

• PR Install Rust for piwheels user with rustup piwheels/piwheels#322
• PR Install rustup as piwheels user piwheels/piwheels#328

Is this still relevant now that cryptography's wheel is now available from piwheels? Ref: #3493

[holta]

Good question:

Testing will positively confirm on 32-bit (especially) RasPiOS in coming weeks.

While most everyone (except for legacy RPi Zero W users) should very strongly consider 64-bit RasPiOS going forward.

All cleared up. Calibre-Web once again now runs well on 32-bit RasPiOS:

• Block iiab-install of JupyterHub & Calibre-Web on 32-bit OS's, til RasPiOS fixes Rust, wheels / cryptography #3422 (comment)
• 7db4dc5 part of PR venv refinements for consideration, to tighten up scripts/ansible, deferring install of pip unless truly nec #3496 (to be merged shortly)
