How to Check if You Have the Latest Version
You can check which version of Ubuntu you have installed from your desktop’s settings window or by running a command in a terminal window.
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 21.10 to Ubuntu 22.04 LTS. You can upgrade from Ubuntu 20.04 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 22.04 LTS to Ubuntu 22.10—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.

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.
