How to Upgrade to Ubuntu 20.04 from Ubuntu 18.04 and Ubuntu 19.10. Users can easily update to Ubuntu 20.04 from Ubuntu 19 and Ubuntu 18 Systems.
Upgrade To Ubuntu 20.04
- Go to Software & Updates application and in the Updates tab, check that Notify me of a new Ubuntu version is set to “For long term support versions”
- On versions of Ubuntu prior to 18.04, press the Superkey (Windows key) to launch the Dash and search for Update Manager.
- For Ubuntu 18.04 or later, click on the Show Applications icon in the bottom left of the desktop and search for Update Manager.
- As the application launches it will first check if there are any updates for your current version of Ubuntu that need to be installed. If it does find any, install these first and run Update Manager again if you need to restart your machine.
- Update Manager will open a window to inform you that your computer is up to date. Click on the Settings button to open the main user-interface.
- Select the tab called Updates, if not already selected. Then set the Notify me of a new Ubuntu version dropdown menu to either For any new version or For long-term support versions, if you’re wanting to update to the latest LTS release. You may be asked for your password to make this change.
- Click on Close to be taken back to the update pane and OK to close this.
- We now need to open Update Manager one more time, only this time Update Manager will open up and tell you that a new distribution is available. Click Upgrade.
If No Upgrade Appears
You can force the upgrade, however, with the following steps:
- close Update Manager if it’s still running
- open a terminal in the same way you opened Update Manager
- type update-manager -d and press enter
After asking for your password, you will be presented with the Release Notes for the release you’re about to upgrade to. Select the Upgrade button to start the initialisation process. A few moments later you’ll be asked Do you want to start the upgrade? Press Start Upgrade to pass the point of no return and start the upgrade process.
The upgrade will now proceed. The Distribution Upgrade pane will track the upgrade process and allow you to monitor progress. As the process is dependent on both your network connection and the performance of your computer, the upgrade could take anything from ten or 20 minutes to an hour or more.
After the new packages are installed, you may be asked whether you want to remove any obsolete packages. These are packages that were installed on your previous version of Ubuntu but are no longer required by the new one. You can safely select Remove.
Finally, you’ll be asked to restart the system to complete the upgrade.
Updating via Terminal
Run the following commands in terminal to update Ubuntu:
sudo apt update
sudo apt full-upgrade
sudo do-release-upgrade -d
