What it is

Ubuntu Update Manager is a free graphical frontend for apt that installs available updates and supports routine Ubuntu system upgrades. In the desktop menu it appears as Software Updater, and Ubuntu describes the package as a GNOME application for managing apt updates. It is intended for daily system upgrading as well as migration to a newer Ubuntu release.

The tool can check whether a new distribution release is available. Its development-release option can upgrade from the latest supported release to the development release. During an upgrade, it may reinstall ubuntu-desktop, change sources.list entries to updated ones, and add the default user to new groups when needed. Ubuntu says its bundled installation tools validate packages during installation to check for manipulation during download. Update Manager runs on Linux and integrates with apt. The manpage credits Michael Vogt and various contributors with its development; it also states that redistribution is permitted under the GNU General Public License and provides no warranty.
