Which command would you use to update packages in a Debian-based system?

Updating packages in a Debian-based system is effectively accomplished using the command associated with the Advanced Packaging Tool (APT). The apt command provides a user-friendly interface for managing software packages.

In the context of Debian and its derivatives (like Ubuntu), APT performs functions such as installing, removing, and updating packages efficiently. When you want to update the package list from repositories and upgrade the installed packages, you would typically use commands like apt update followed by apt upgrade.

Other commands listed serve different purposes or relate to different types of Linux distributions. For instance, tar is used for archiving files and directories, but it has no direct role in package management. The rpm command is utilized in Red Hat-based distributions for managing RPM packages, while zypper is the package manager for openSUSE and other SUSE-based systems. Thus, APT is specifically designed for Debian-based systems, making it the correct choice for updating packages within that environment.
