What is the Ubuntu OS?
Ubuntu OS is a free and open-source Linux distribution based on Debian. Ubuntu is officially released in three editions: Desktop, Server and Core (for the internet of things devices and robots). All the editions can run on the computer alone, or in a virtual machine. Ubuntu is a popular operating system for cloud computing, with support for OpenStack.
Ubuntu OS is released every six months, with long-term support (LTS) releases every two years. The latest release is 19.10 (“Eoan Ermine”), and the most recent long-term support release is 18.04 LTS (“Bionic Beaver”), which is supported until 2023 under public support and until 2028 as a paid option.
Ubuntu OS is developed by Canonical, and a community of other developers, under a meritocratic governance model. Canonical provides security updates and support for each Ubuntu release, starting from the release date and until the release reaches its designated end-of-life (EOL) date. Canonical generates revenue through the sale of premium services related to Ubuntu.

Create professional documents, spreadsheets and presentations on Ubuntu with LibreOffice, the open-source office suite that’s compatible with Microsoft Office. That means you can open and edit files like Word documents, Excel spreadsheets, and PowerPoint presentations and share them with other users quickly and easily. You can also use Google docs directly from your desktop.
Renowned for speed and security, Ubuntu and Firefox make browsing the web a pleasure again. Ubuntu also includes Chrome, Opera and other browsers that can be installed from the Ubuntu Software Centre.
Ubuntu comes with Thunderbird, Mozilla’s popular email application, so you’ll have fast desktop access to your email. No matter which email services you use; Microsoft Exchange, Gmail, Hotmail, POP or IMAP, email just works.
Ubuntu is full of free apps to help you enjoy, manage, edit and share your photos — whatever you use to take them. With fantastic support for cameras and phones, you won’t need any extra drivers to get up and running.
Edit and illustrate
Edit your photos or create professional illustrations and designs with tools like Gimp and Inkscape, available in the Ubuntu Software Centre.
Organize your photos
With Shotwell, you can quickly and easily import, organize, edit and view your pictures. And you can share your favorite snaps on all popular photo sites and social networks.
Watch all your favorite content on Ubuntu with apps for playing, managing and sharing your videos. Edit your movies with PiTiVi and then watch them in Movie Player — or add VLC and OpenShot from the Ubuntu Software Centre, for compatibility with even more file formats.
An open-source operating system
The code is shared openly throughout the development cycle. We are transparent about our plans for future releases, so as a developer, hardware manufacturer, or OEM, you can work with us to start building Ubuntu applications and systems now.
Backed by Canonical
Canonical is the global software vendor that provides commercial, design and engineering support to the Ubuntu project. Today, our hardware enablement team supports the pre-installation of Ubuntu on more than 10% of all new PCs shipped, worldwide.
The Latest LTS Version is Ubuntu 18.04 LTS “Bionic Beaver”
The newest long-term support release of this Linux distribution is Ubuntu 18.04, codenamed “Bionic Beaver”. It uses version 4.15 of the Linux kernel.
Ubuntu 18.04 “Bionic Beaver” is the first long term support release to ditch Ubuntu’s Unity desktop and replace it with GNOME Shell. This comes after Canonical gave up on Ubuntu for phones and set aside the vision of “convergence” they had back in Ubuntu 17.10.
Ubuntu is now focused on being a powerful, stable Linux desktop that brings together the best Linux software out there. Canonical isn’t trying to reinvent the wheel with projects like Unity 8 and the Mir display server anymore. Even the window buttons are back in the top right corner of each window instead of the top left corner. This isn’t all bad, though—Ubuntu 18.04’s GNOME Shell is a slick, polished desktop.
How to Check if You Have the Latest Version
If you’re using the standard version of Ubuntu with either the newer GNOME Shell or older Unity desktop, click the icon at the top right corner of your desktop and click either the Settings icon or the “System Settings” option in the menu. Click the “Details” option in the left sidebar or click the “Details” icon under System if you see a window with a variety of icons.
You’ll see the version of Ubuntu you’re using here. You can also run the “
lsb_release -a” command in a terminal window to find this information on any edition of Ubuntu.
How to Upgrade to the Latest Version
You can always upgrade from one Ubuntu release to the next one. For example, you can now upgrade directly from Ubuntu 17.10 to Ubuntu 18.04 LTS. You can upgrade from Ubuntu 16.04 LTS, too.
If you’re running an LTS version of Ubuntu and want to upgrade to a non-LTS version—for example, if you want to upgrade from Ubuntu 18.04 LTS to Ubuntu 19.04—you’ll need to tell Ubuntu you want to see “any new version,” not just “long-term support versions.” This option is available at Software & Updates > Updates > Notify me of a new Ubuntu version.
To upgrade to the latest available version of Ubuntu, press Alt+F2, type the following command, and press Enter:
If you don’t see a message telling you the new release is available, press Alt+F2, type the following command, and then press Enter:
You’ll see a message telling you a new release is now available if one is. Click “Yes, Upgrade Now” to install it on your system
You can also upgrade from the terminal by running the
sudo do-release-upgrade command. You may need to run the
sudo apt install update-manager-core command first to install it. Edit the
/etc/update-manager/release-upgrades file to choose which versions of Ubuntu the tool installs.
