Adapting a docker image to Home Assistant add-on

Hi All
I am trying to convert a docker image (that has Apache and Perl) to work as a HASS.io add-on, and every time I try to install, it flashes red, and it doesn’t display any error. Is there any way I can debug this? What am I doing wrong

Here is the dockerfile:

FROM hassioaddons/debian-base-armhf:0.2.2

RUN \
    DEBIAN_FRONTEND=noninteractive && \
    apt-get update && \
    apt-get install -y \
        build-essential \
        apt-utils \
        ssl-cert \
        apache2 \
        apache2-utils \

    apt-get update -y && \
    apt-get upgrade -y && \
    apt-get -y clean
