What package management tools are available to users in the Ubuntu distribution?

Ubuntu distribution offers several tools for package management:

• APT (Advanced Package Tool) — the main tool for installing, updating, and removing packages in .deb format. Used via apt or apt-get commands.

• dpkg — a low-level tool for managing .deb packages, allowing installation, removal, and information retrieval about packages.

• Snap — a packaging and containerization system from Canonical, enabling applications to be installed in isolated environments.

• Flatpak — an alternative system for installing applications in isolated containers, supported in Ubuntu.

Example of installing a package via APT:

sudo apt update
sudo apt install nginx

Thus, Ubuntu provides flexible options for managing software both from standard repositories and external sources.
