apt-get update failing when building a docker image with ubuntu - docker

Question

I am trying to build a docker image using ubuntu:latest on a Mac. I am using a shell file to collect the set up steps but the building stops when the container runs apt-get update.
The error is:
Ign:1 http://archive.ubuntu.com/ubuntu jammy InRelease
Ign:2 http://security.ubuntu.com/ubuntu jammy-security InRelease
Ign:3 http://archive.ubuntu.com/ubuntu jammy-updates InRelease
Ign:2 http://security.ubuntu.com/ubuntu jammy-security InRelease
Ign:4 http://archive.ubuntu.com/ubuntu jammy-backports InRelease
Ign:2 http://security.ubuntu.com/ubuntu jammy-security InRelease
Ign:1 http://archive.ubuntu.com/ubuntu jammy InRelease
Err:2 http://security.ubuntu.com/ubuntu jammy-security InRelease
Connection failed [IP: 185.125.190.39 80]
My Dockerfile is:
FROM ubuntu
RUN chmod +x set_up.sh
RUN ./set_up.sh
while set_up.sh is
#!/bin/sh
#1. Update package manager
apt-get update
For context, I get the same error if I use
docker run --rm -it ubuntu:latest /bin/bash
root#fca959160783:/# apt-get update

I am new to docker but I've been running the same code yesterday on a different WiFi connection and I didn't experience any issue. I have tried adding the options --network=host to the build command or my current DNS IP address in the docker run version of the example but I get the same issues and I am not sure what to do now. I'd appreciate any suggestions you might have on this issue.
Thanks a lot for your help!

Answer 1

It could be architecture mismatch.
Check docker architecture with: docker info | grep Architecture
Check image architecture with: docker inspect ubuntu
In the case of mismatch you should reinstall docker.
