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 downloading packages with apt-get install, even immediately after running apt-get -y update. For instance, today I see
Err http://archive.ubuntu.com/ubuntu/ trusty-security/main libxml2 amd64 2.9.1+dfsg1-3ubuntu4.7
404 Not Found [IP: 91.189.88.161 80]

Apparently the specific version of a particular package has been deleted from the archive and replaced with a slightly differently named patch version. For instance, the above error is looking for libxml2_2.9.1+dfsg1-3ubuntu4.7_amd64.deb but the version on the server is libxml2_2.9.1+dfsg1-3ubuntu4.8_amd64.deb.
Often this is solvable by removing the base image (docker rmi ubuntu:14.04) and rebuilding; the newly downloaded ubuntu image has the correct patch number and finds the right archive file. But even this doesn’t always work — probably due to a delay between a new minor upgrade to Ubuntu’s dependency db and the deployment of that new ubuntu:14.04 image onto Docker Hub.
We’ve tried using apt-get flags --fix-missing and --fix-broken and those don’t consistently work either.
Any other ideas?
apt-get install fails with Not Found error because package removed from repository is a similar problem but the accepted answer is unacceptable because it’s not possible to be automated. Our daily development process, including automatic build and deploy, is all scripted and using Docker and it’s not practical to hack around inside a Dockerfile every time a particular archive goes missing (then remove the hack after a few hours or days).
In response to @prateek05, here’s the /etc/apt/sources.list from the official ubuntu:14.04 docker image:
