Common Package Management Operations

Common package management operations involve installing, updating, upgrading, removing, and cleaning software packages to keep a Linux system secure, up to date, and properly maintained.

1. Update package list:

Updates the local package index with the latest information from configured repositories. It does not install or upgrade packages but ensures the system knows about available updates.

apt update

2. Upgrade installed packages:

Upgrades all installed packages to their latest available versions based on the updated package list, without removing existing packages.

apt upgrade

3. Remove a package:

Uninstalls the specified package from the system while keeping its configuration files intact.

apt remove package_name

Clean unused packages:

Removes automatically installed packages that are no longer required, helping free up disk space and keep the system clean.

apt autoremove
