In Docker, apt-get install fails with “Failed to fetch http://archive.ubuntu.com/ … 404 Not Found” errors. Why? How can we get past it?

Question

My team uses Docker (with ubuntu:14.04 base image) for local development and we often have to rebuild some or all of our images. But we often get failures downl

Answer 1

In my case the problem was caused by the parent image since it had not cleared the apt cache properly.

I solve the problem including cleaning commands before the first apt update ...

RUN apt clean && \
    rm -rf /var/lib/apt/lists/* && \
    apt update && \
    ...

Hope this helps
