Apt-get update failed in Docker container: How to solve the problem of Alibaba Cloud's image source configuration?

apt-get update failed in Docker container: Detailed explanation of Alibaba Cloud image source configuration and solution

This article analyzes the problem that the apt-get update command fails after modifying the /etc/apt/sources.list file when using the official PHP 5.6-fpm image. The user tried to use the Alibaba Cloud image, but encountered errors such as "release file missing" and "url redirection target contains control characters".

The problem stems from the user directly replacing all sources in the /etc/apt/sources.list file, using the following Alibaba Cloud image configuration:

 <code>deb http://mirrors.aliyun.com/debian/ stretch main non-free contrib deb-src http://mirrors.aliyun.com/debian/ stretch main non-free contrib deb http://mirrors.aliyun.com/debian-security stretch/updates main deb-src http://mirrors.aliyun.com/debian-security stretch/updates main deb http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib deb-src http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib</code>

This causes apt-get update to fail, prompting the release file missing, and URL redirection issues. The root cause is that the PHP 5.6-fpm image is based on older Debian systems (stretch, Debian 9), which no longer supports all the components listed in the user configuration.

The correct solution: Avoid completely replacing the source and only replacing the official Debian source as Alibaba Cloud image. Use the following command to execute in a new container:

 sed -i 's/deb.debian.org/mirrors.aliyun.com/;s/security.debian.org/mirrors.aliyun.com/' /etc/apt/sources.list

This command replaces all addresses pointing to deb.debian.org and security.debian.org in the /etc/apt/sources.list file with Alibaba Cloud mirrors mirrors.aliyun.com , thereby solving the compatibility issue and ensuring that apt-get update is successfully executed. Be sure to do this in a new container to ensure the modification takes effect.
