Set DEBIAN_FRONTEND=noninteractive before running apt-get install:

ARG DEBIAN_FRONTEND=noninteractiveRUN apt-get update && apt-get install -y ...UPD1:Just to add bit more context, it is not esl-erlang that is causing it, instead this prompt comes from installing tzdata.

sudo ln -s /usr/share/zoneinfo/America/<CITY> /etc/localtimewhere CITY is one of the cities from ls /usr/share/zoneinfo/America/
