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:

  1. Open a terminal by pressing Ctrl + Alt + T.
  2. Update your system using the following command:sudo apt update && sudo apt upgrade
  3. Install the update-manager-core package if it is not already installed using the following command:sudo apt install update-manager-core
  4. 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.
  5. Start the upgrade process by running the following command:sudo do-release-upgrade
  6. Follow the on-screen instructions to complete the upgrade process.
  7. After the upgrade is complete, reboot your system:sudo reboot


Using the graphical user interface (GUI) to upgrade your system is a similar process. Here are the steps:

  1. Open the "Software & Updates" application.
  2. Click on the "Updates" tab.
  3. Under "Notify me of a new Ubuntu version", change the value to "For any new version".
  4. Close the "Software & Updates" application.
  5. Open the "Software Updater" application.
  6. Click on the "Upgrade" button.
  7. Follow the on-screen instructions to complete the upgrade process.
  8. After the upgrade is complete, reboot your system.
