Problems with ubuntu:20.04

[aminya]

setup-cpp requires Node 12 or higher. Here I added a docker file for installing Nodejs on Ubuntu 20:

setup-cpp/dev/docker/setup-cpp-ubuntu-20.0.4.dockerfile

Lines 4 to 13 in e2b11c4

	RUN apt-get update -qq && \
	# install latest nodejs on ubuntu 20.04
	apt-get update -qq && \
	apt-get install -y --no-install-recommends curl gnupg ca-certificates && \
	mkdir -p /etc/apt/keyrings && \
	curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg && \
	echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_20.x nodistro main" | tee /etc/apt/sources.list.d/nodesource.list && \
	apt-get update -qq && \
	apt-get install -y --no-install-recommends nodejs && \
	# install setup-cpp

Alternatively, you can use the binaries that are self-contained:
