When building this container I run into
# wget https://github.com/timower/rM2-stuff/releases/download/v0.1.2/rm2display.ipk
# Connecting to github.com (140.82.121.3:443)
# wget: note: TLS certificate validation not implemented
# wget: error getting response: Connection reset by peer
I think this might be the same error as docker-library/busybox#162
