To upgrade on a server system:

Note that the server upgrade will use GNU screen and automatically re-attach in case of dropped connection problems.

There are no offline upgrade options for Ubuntu Desktop and Ubuntu Server. Please ensure you have network connectivity to one of the official mirrors or to a locally accessible mirror and follow the instructions above.

Snap application format

Ubuntu 16.04 LTS introduces a new application format, the ‘snap’, which can be installed alongside traditional deb packages. These two packaging formats live quite comfortably next to one another and enable Ubuntu to maintain its existing processes for development and updates. More information is available here.

Updated Packages

As with every new release, packages–applications and software of all kinds–are being updated at a rapid pace. Many of these packages came from an automatic sync from Debian’s unstable branch; others have been explicitly pulled in for Ubuntu 16.04.

For a list of all packages being accepted for Ubuntu 16.04, please subscribe to xenial-changes.

Linux kernel 4.4

Ubuntu 16.04 LTS is based on the long-term supported Linux release series 4.4.
