Fetch Old Release Archies in Ubuntu
Rcently, when building a MySQL 5.6 Docker in Ubuntu 14.04, got errors:
Bash
W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/trusty-security/universe/source/Sources 404 Not Found [IP: 91.189.88.41 80]

E: Some index files failed to download. They have been ignored, or old ones used instead.
This approach works well before, and just because some updates made in the Dockerfile, and cause to redownload the MySQL 5.6.
This is because the offical source security of ubuntu 14.04 is out of date, so, we can change it to a mirror source to fix the issue.
For example, replace the security by running following command before apt update in the Dockerfile.
