I'm trying to create a multi-arch container based on ubuntu 20.04. Docker build fails on apt update after the new architecture is added. This is my docker file so far:

# base image
FROM ubuntu:20.04

create user


RUN useradd -rm -d /home/embed -s /bin/bash -g root -G sudo -u 1001 embed
RUN mkdir -p /home/embed/software
RUN mkdir -p /home/embed/data


symlink python3 to python


RUN ln -s /usr/bin/python3 /usr/bin/python


install arm64 cross-compilation toolchain


RUN dpkg --add-architecture arm64
RUN apt-get update
...

After it reaches apt-get update, I get the following output:

It seems that all arm64 repositories are either ignored or not found. I found this question that has the exact same problem, but no solution is provided.

Do I have to arch-qualify all the apt sources before doing an apt-update like this answer says? Is there a more automatic way that suits building a docker image?

Thanks in advance

    You're using the wrong archive URLs. arm64 exists on ports.ubuntu.com not the main archive.u.c – Thomas Ward Jan 13 '21 at 14:58
  • @ThomasWard I realize that. I was wondering if there's a clean/correct way of doing it rather than manually arch qualifying the old ones. – M47 Jan 13 '21 at 16:56

I still don't know if there's a better way of doing this but I basically did what's done here, but for 20.04. The Dockerfile is now:

# base image
FROM ubuntu:20.04

...


add arm64 architecture


RUN apt-get update
RUN dpkg --add-architecture arm64


arch-qualify the current repositories


RUN sed -i "s/deb h/deb [arch=amd64] h/g" /etc/apt/sources.list


add arm64's repos


RUN echo "# arm64 repositories" >> /etc/apt/sources.list
RUN echo "deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports focal main restricted" >> /etc/apt/sources.list
RUN echo "deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports focal-updates main restricted" >> /etc/apt/sources.list
RUN echo "deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports focal universe" >> /etc/apt/sources.list
RUN echo "deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports focal-updates universe" >> /etc/apt/sources.list
RUN echo "deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports focal multiverse" >> /etc/apt/sources.list
RUN echo "deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports focal-updates multiverse" >> /etc/apt/sources.list
RUN echo "deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports focal-backports main restricted universe multiverse" >> /etc/apt/sources.list
RUN echo "deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports focal-security main restricted" >> /etc/apt/sources.list
RUN echo "deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports focal-security universe" >> /etc/apt/sources.list
RUN echo "deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports focal-security multiverse" >> /etc/apt/sources.list


RUN apt-get update
...
