Raspberry Pi Powered live Train station monitor

Hi I posted a comment on the blog post about the live train station monitor as I’m having issues pushing the file to balena. Chris suggested posting a topic here to work out what is going wrong.

This is the full build log:

For CLI bug reports or feature requests, have a look at the GitHub issues or

Hopefully this helps identify the issue.


Gregor, for this one, I’ll attempt to duplicate this, but as a quick test, in the Dockerfile, try replacing %%BALENA_MACHINE_NAME%% with ‘raspberrypi3’ (without the quotations). I suspect this is an issue with using a 64-bit container.


I tried changing this but I got the same error code.


Thanks Gregor, we had a look at this, and indeed something about the pip installation process changed, that we were unaware of. We’ve pushed an update that solves the issue, and, if you re-download the application (or delete it and git clone it once again), you should be able to build it successfully now. Thanks for brining it to our attention!

Brilliant, I’ll try it justnow!

That seems to have solved it! Thanks for the help!

Great, thanks for letting us know this broke!
