Linux server ubuntu download

Ubuntu 20.04.3 LTS (Focal Fossa)

Select an image

Ubuntu is distributed on three types of images described below.

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 1024MiB of RAM to install from this image.

Choose this if you have a computer based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). Choose this if you are at all unsure.

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.

Choose this if you have a computer based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). Choose this if you are at all unsure.

A full list of available files, including BitTorrent files, can be found below.

If you need help burning these images to disk, see the Image Burning Guide.

Infrastructure and applications foundation

From public clouds to data centres to devices

Ubuntu is the most popular guest operating system on public clouds, the foundation for private clouds implementation and the platform of choice of developers according to the 2020 HackerEarth Developer Survey.

Juju — multi-cloud orchestration

With the option of a command line or browser-based interface, Juju enables you to design and deploy entire workloads in just a few clicks. It works on public clouds like AWS and Microsoft Azure, private clouds built on OpenStack and even directly on bare metal, via MAAS.

MAAS — bare metal provisioning

MAAS is a time-saving provisioning system which makes it quick and easy to set up the physical hardware to deploy complex services, like Ubuntu’s OpenStack cloud infrastructure. Just plug in your servers, connect them to the network and let MAAS do the rest.

LXD — machine containers

Economics are directly tied to compute density. LXD, the Linux container hypervisor, merges the speed and density of containers with the manageability and security of traditional virtual machines.

Ubuntu Advantage for your Infrastructure

Ubuntu Advantage for infrastructure offers a single, per-node packaging of the most comprehensive software, security and IaaS support in the industry. With OpenStack and Kubernetes support included, Ubuntu Advantage for Infrastructure provides everything you need to future-proof your data centre.
