unable to build docker image on ubuntu on RPi

[sandeep-gh]

Hello,

I am trying to build python3.10 on termux and for that was creating Docker build environment on ubuntu which is running on RPi4.
However, the command docker build -t termux/package-builder . fails with error:
E: Failed to fetch http://ports.ubuntu.com/ubuntu-ports/dists/focal/restricted/binary-i386/Packages 404 Not Found [IP: 91.189.91.39 80].

None of the suggestion mentioned on the web seems to be applicable here. Is there something I need to change in setup-ubuntu.sh?

Thanks

Sorry, Docker image can be built only for x86_64. Reason is mainly for Android NDK and SDK. However rest expects x86_64 machine anyway.

Got it. Thanks for the note. Will try on x86 machine then.
