This hardware is not supported, sorry!

The manual install of the library works sudo apt-get install python3-blinkt

With that I was able to run rainbow.py from the Getting Started with Blinkt!

Looks like I'd better get my skates on and allow installs on 64bit - https://www.raspberrypi.com/news/raspberry-pi-os-64-bit/

I've just installed this on a Pi 3B, with the official 64 bit OS.

I downloaded the script and removed the two tests that were failing:
arch_check() was reporting it as aarch64, so I changed the code to report it as armhf.
OS_NAME was reported as Debian, so I changed that code to report Raspbian.

The rest of the procedure was unchanged, and it works fine! So hopefully @Gadgetoid doesn't have a lot to do...

(edited to correct the architecture)

Thank you @mahood73 that's helpful.

I'm starting to wonder if the OS check is all that much use, since "Debian/aarch64" is pretty generic. It might just need ripping out. I'm tending toward less complicated installer scripts, since these are a legacy holdout from when I had a helping hand working on them and thus a nightmare to maintain.

[Gadgetoid]

I have unceremoniously deleted all OS, arch and system checks from the installers- inserting a slightly louder warning about running only on a Raspberry Pi. Hopefully this will get us away from the brick wall OS compat message to actually discovering if there are any incompatibilities (I doubt it.)

Installer should hopefully work now!

[Gadgetoid]

Hopefully I haven't regressed any of this in #102

Any update on support for Pi 5 and 64bit?

WARNING Wall of text to follow!!
Latest Pi OS 64 bit on a Pi 4B
I got an example to run from command line.
Thonny just coughed up blink has no attribute... errors.
I have no idea what to do after you reboot to get an example to run?
