Upgrading your Ubuntu system to a new Long Term Support (LTS) release can be done through the terminal or through the graphical user interface (GUI). Here are the steps to upgrade using the terminal:
- Open a terminal by pressing Ctrl + Alt + T.
- Update your system using the following command:sudo apt update && sudo apt upgrade
- Install the update-manager-core package if it is not already installed using the following command:sudo apt install update-manager-core
- Open the /etc/update-manager/release-upgrades file using a text editor such as nano or gedit:sudo nano /etc/update-manager/release-upgrades
Change the value of Prompt from lts to normal:Prompt=normal
Save and close the file.
- Start the upgrade process by running the following command:sudo do-release-upgrade
- Follow the on-screen instructions to complete the upgrade process.
- After the upgrade is complete, reboot your system:sudo reboot

- Close the "Software & Updates" application.
- Open the "Software Updater" application.
