Default snaps for fixgateway are failing importing Numpy

[EdB987]

I've been cleaning up my install and wanted to try CarPiHat hat for a more reliable power on/power off solution because the X729 + RPi5 simply gets itself into a confused state if power cycled too many times. It is impossible to resolve in flight because the pi is behind my seat. In any case, I want the unit to power on and off reliably with a switch.

That being said, I have opted for a completely clean install. It seems that the current production fixgateway snap is failing when loading the mgl plugin and mgl wants to import Numpy. There is a dependency on libblas.so.3, which is not present in the build.

Steps to reproduce:

Enable mgl (not mgl_serial) and run fixgateway manually with --debug set:

fixgateway.server --config-file=$HOME/makerplane/fixgw/config/default.yaml --debug

output is:

CRITICAL:20250222-12:09:06:root - Unable to load module - fixgw.plugins.mgl: Error importing numpy: you should not try to import numpy from
its source directory; please exit the numpy source tree, and relaunch
your python interpreter from there.

During handling of the above exception, another exception occurred:

Further down:
Original error was: libblas.so.3: cannot open shared object file: No such file or directory

If you run sudo snap refresh it should update fixgateway and hopefully work OK now.
I updated the LD_LIBRARY_PATH env var so it can find libblas.so.3

To tell if you are running the fixed version run snap list, the Rev column should report 226 (amd64) or 227 (arm64) for fixgateway, or possibly a higher number if other changes are pushed after I post this message.

Works perfectly. Thank you.
