Here you can download the official Ubuntu 16.04 LTS “Xenial Xerus” ISO for free.
Shuttleworth announced on 21 October 2015 that Ubuntu 16.04 LTS would be called Xenial Xerus and include an option for Unity 8. It was released on 21 April 2016. In September 2021, Canonical announced that it would extend LTS support for the 14.04 and 16.04 to a total of 10 years, extending the ESM support date for 16.04 until April 2026. The release adds support for Ceph and ZFS filesystems, the LXD hypervisor for OpenStack, and Snap packages. It uses systemd instead of Upstart as its init system.
This release has online Dash search results disabled by default in Unity 7, does not support the AMD Catalyst (fglrx) driver for AMD/ATI graphics cards, and instead recommends the Radeon and AMDGPU alternatives. It also replaced the Ubuntu Software Center with GNOME Software (rebranded as “Ubuntu Software”) and eliminated Empathy and Brasero from the ISO file.
Desktop image
The desktop image allows you to try Ubuntu without changing your computer at all, and at your option to install it permanently later. This type of image is what most people will want to use. You will need at least 384MiB of RAM to install from this image.
There are two images available, each for a different type of computer:
64-bit PC (AMD64) desktop image
Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the i386 images instead. Choose this if you are at all unsure.
32-bit PC (i386) desktop image
For almost all PCs. This includes most machines with Intel/AMD/etc type processors and almost all computers that run Microsoft Windows, as well as newer Apple Macintosh systems based on Intel processors.
Server install image
The server install image allows you to install Ubuntu permanently on a computer for use as a server. It will not install a graphical user interface.
