Build fails when using Dockerfile.template (missing curl & unexpected end of file)

[fellwell5]

Hello!

When using the provided Dockerfile.template, I am running into issues while building the image.

1. Missing curl

curl is not installed in the base image, so I added it to the apt-get install command.

2. Build error: gzip: stdin: unexpected end of file

After adding curl, the image build fails with the following error:

gzip: stdin: unexpected end of file
tar: Child returned status 1
tar: Error is not recoverable: exiting now

Dockerfile (hidden in spoiler)

    | tar -xvz -C  /usr/src/app/ui 

COPY scripts/start.sh .

CMD ["bash", "start.sh"]

Question

Does anyone know how to resolve this error?
It seems like the downloaded archive may be corrupted or unavailable for the detected architecture, but I am unsure how to fix it.

Best regards,
Matthias

Confirm I have the same issue, building to Balena device using a Mac. I am pushing to a raspberry pi 4 so the correct release is:
https://github.com/balena-os/wifi-connect/releases/download/v4.11.84/wifi-connect-aarch64-unknown-linux-gnu.tar.gz

When I replaced the if/else results with this above link I still get an unexpected end of file. After some digging I accidentally solved it, we need to add both curl and ca-certificates for the code to finalize as written with the image it currently uses.

Line 3 is now:
RUN apt-get update && apt-get install -y --no-install-recommends dnsmasq wireless-tools curl ca-certificates
