Configuring APT sources.list: A Quick Reference Guide for Debian Systems
When working with Debian systems, it’s crucial to have the right APT sources.list configuration for accessing software packages. This is especially true in situations where you’re setting up a new system, recovering from a failure, or maintaining older versions of Debian. The APT sources.list file tells the Advanced Package Tool (APT) where to fetch packages from. This guide aims to provide a quick reference for setting up the APT sources.list on various Debian systems, covering both current and archived versions. It’s important to note that when Debian versions are no longer supported, their repositories are moved to an archive status. In such cases, it is necessary to update the sources.list file by replacing the ‘deb’ URLs with ‘archive’ URLs to continue accessing packages.
How to integrate any Linux distribution inside a terminal with Distrobox
Distrobox is a free and open source tool which allows us to integrate the userlands of Linux distributions.

How to configure Certificate Authority on Ubuntu/Debian
A Certificate Authority plays a vital role in ensuring and verifying secure connections between clients and servers. When you try to connect to a remote server – let’s say a website, for example – how does your system know that it is connecting to the right place? After all, there is nothing stopping any rogue system from claiming itself as a website which it is actually not. This is where certificate authority servers come into play, by helping our client system verify that we are connecting to the intended server. This particular example is in the context of a website connection, so would involve the HTTPS protocol, but certificate authorities can also be used to authenticate other types of connections, such as VPN.
