#Upgrade Ubuntu 20.04 LTS to 22.04 using a Graphical interface
Many Ubuntu Desktop Linux users are not much familiar with commands and prefer graphical elements to install and manage things. Also, it is easy to manage the system using GUI instead of commands. Hence, if you are one of those users then here are the steps to follow.
Open Ubuntu 20.04 Software updater
The first thing we have to make sure that our existing installed packages on Ubuntu 20.04 are up to date. So, that we won’t get any compatibility issues while upgrading the same. Therefore, go to Application launcher and search for Software update, when it appears, click to open the same.
Once the app is launched, it will check for the available updates.
If there are any updates available you will be notified of the same along with the size of packages, and the app will fetch. You just have to click on the “Install Now” button.
Open Software & Updates
Once the system is updated, again go to the Application launcher and this time open “Software & updates“.
Go to Updates Tab and for “Notify me of a new Ubuntu version” select “For long-term support versions” from the drop-down box. After that simply close the app.
Open command box
To open the command box, simply press Alt+F2 on your keyboard. This will open a graphical box to run commands. There paste the given command to let the system check any available upgrade.
update-manager -c -d
Ubuntu 22.04 is now available (you have 20.04)
After running the command in the above step, you will get a pop-up notifying you that the upgrade to Ubuntu 22.04 is available for your current 20.04 LTS system. Hence, if you want to proceed then hit the “Upgrade” button.
It will ask for your User’s password to authenticate.
