When updating Ubuntu and encountering “The following packages have been kept back,” it indicates manual intervention is needed due to dependency issues. You can cautiously upgrade these packages using specific apt-get commands or opt for a more aggressive approach with `dist-upgrade`, which handles complex dependencies by potentially adding or removing packages. Understanding each method’s implications is crucial for system stability.
In this guide, we explore how to update a single package on Debian and Ubuntu systems using APT. Unlike `apt-get upgrade`, which updates all packages, `apt-get install –only-upgrade ` allows for updating specific packages. This command is essential for maintaining system stability without unnecessary updates. We also cover checking for updates, holding packages, and automating updates with cron jobs, providing system administrators with precise control over their package management.

Rootless Docker allows you to run Docker containers without requiring root access, improving security and compliance, simplifying management, and enhancing portability. Running Docker as a regular user reduces the risk of security vulnerabilities and enables compliance with policies. Rootless Docker is also easier to integrate into workflows and makes it simpler to move containers between different environments.
Docker is a popular platform for creating, deploying, and managing applications in containers. Containers provide a lightweight and portable way to package applications with their dependencies, making it easier to move them between environments and ensuring consistency across different platforms. Docker simplifies the process of building, shipping, and running applications, making it easier to develop, test, and deploy software in a fast and efficient way. It is widely used by developers, IT professionals, and organizations of all sizes to improve the efficiency, scalability, and portability of their applications.
