Docker build “Could not resolve 'archive.ubuntu.com'” apt-get fails to install anything

Question

I\'ve been trying to run Docker build on various files which previously worked before, which are now no longer working.

As soon as the Docker file included any line

Answer 1

I run into the same problem, but neiter uncommenting /etc/default/docker dns entries nor editing the /etc/resolv.conf in the build container or the /etc/docker/daemon.json helps for me.

But after I build with the option --network=host the resolving was fine again.

docker build --network=host -t my-own-ubuntu-like-image .

Maybe this will help someone again.
