Installing pi-hole in Docker Container

Question

I have a Ubuntu based docker container. I am trying to install pi-hole in it. The commands for installation are in my base.dockerfile. The commands are: FROM ubuntu:latest # Commands for pi-hole RUN echo 'debconf debconf/frontend select Noninteractive' | debconf-set-selections RUN echo -e "\nexport TERM=xterm" >> ~/.bashrc

    RUN apt-get update && apt-get install -y \
        curl \
        && curl -sSL https://install.pi-hole.net | bash

    RUN \
        apt-get update --fix-missing\
        && apt-get install -y --no-install-recommends \
        && rm -rf /var/lib/apt/lists/*

However, I am getting the following error:

I am a bit confused as I am pretty new to this.

Any suggestions or leads are appreciated.

Thanks.

Can you extract the text content from that PNG file, and replace the image with that? Including the entire Dockerfile (and especially the `FROM` line) would be helpful too. — David Maze, Nov 28 '19 at 15:17
There's an image for pihole already, why create a new one? Can you use their Dockerfile instead? — BMitch, Nov 28 '19 at 15:54
I have to somehow install pi-hole in the above image. Is there any other way to achieve this? I am really confused — Jishan, Nov 28 '19 at 15:57

This is a typical script error in virtual environments that applies to Docker containers, too. Please try the solutions from this SO question:

One of these:

Run the command set | grep TERM
Run export TERM=xterm
Run export TERM=linux

Seems that you already set `export TERM=xterm` in the dockerfile (second line in the section "Commands for pi-hole"), you can try changing this – schnaader Nov 28 '19 at 15:49
I tried but somehow the commands dont work for me. I am not sure what is wrong with the code. – Jishan Nov 28 '19 at 15:54
