Part of my Dockerfile is as:
RUN apt-get install -yqq software-properties-common
RUN add-apt-repository ppa:ubuntugis/ppa && apt-get update -yqq
RUN apt-get install -yqq gdal-bin
RUN apt-get install -yqq postgis
I installed postgis repo, then installing postgis, but when it got to the installation step of postgis, I get this prompt on the screen & it's stuck there.
debconf: unable to initialize frontend: Dialog
debconf: (TERM is not set, so the dialog frontend is not usable.)
debconf: falling back to frontend: Readline

Does anyone has any idea??
Use RUN DEBIAN_FRONTEND=noninteractive apt-get install -yqq postgis when install postgis to suppress the dialog, or use ARG DEBIAN_FRONTEND=noninteractive which will also not persist to container but still have same effect.
Maybe also refers to https://github.com/docker/docker/issues/4032
