update-manager 命令

常用示例

说明

update-manager is Ubuntu's graphical frontend for the apt package management system. Known as "Software Updater" in the application menu, it provides a user-friendly interface for checking and installing system updates. The tool checks for available package updates, displays them with descriptions and sizes, and allows users to selectively install updates. It also detects when new Ubuntu releases are available and offers to perform distribution upgrades. update-manager handles security updates, regular package updates, and major version upgrades. It integrates with Ubuntu's notification system to alert users when updates are available. For servers or command-line environments, the equivalent functionality is provided by apt or apt-get.
