Issue
The aim is to have a Docker CLI in a Container, so I can Communicate with the Host Daemon from within this Container. Therefore I wanted to connect the socket's in the run Command.
I have a Dockerfile with the following start. The rest of the build works fine when I omit the Curl and Docker CLI part.
FROM ubuntu:20.04 as build
#might be even more slim, yet has not yet been tested: debian-stable-slim
RUN apt-get update \
&& apt-get install -y wget
RUN apt-get update && \
apt-get -y install sudo
RUN apt-get update && \
apt-get install curl
## Install Docker CLI:
ENV DOCKERVERSION=20.10.9
RUN sudo curl https://download.docker.com/linux/static/stable/x86_64/docker-${DOCKERVERSION}.tgz \
&& tar xzvf docker-${DOCKERVERSION}.tgz --strip 1 \
-C /usr/local/bin docker/docker \
&& rm docker-${DOCKERVERSION}.tgz
This is the build log with error message:

executor failed running [/bin/sh -c apt-get update && apt-get install curl]: exit code: 1
there is no possibility to choose Y/n, because it exits instantly. Has anyone a Idea how to solve this?
Im Using Docker on Windows, Version 20.10.8
Thanks a lot!
Solution
apt get install will wait for user input. You're missing the -y flag to allow it to continue without human intervention:
RUN apt-get update && \
apt-get install -y curl
