The Ubuntu operating system is known for its regular updates and upgrades, ensuring users always have access to the latest features, security patches, and software improvements. In this article, we’ll guide you through the process of upgrading from Ubuntu 21.10 to the upcoming Ubuntu 22.04, explaining each step in detail.
Upgrading from Ubuntu 21.10 to 22.04 is a relatively straightforward process. You can upgrade via the command line interface (CLI) using the sudo do-release-upgrade command or through the graphical user interface (GUI) using the Software Updater tool. It’s important to have a stable internet connection and backup your data before starting the upgrade process. Early adopters can modify the package sources to upgrade before the official release, but it’s recommended to test the new release on a separate system or virtual machine.
Prerequisites
Before starting the upgrade process, ensure that you have a stable internet connection and your data is backed up. It’s always a good idea to have a recent backup of your important files in case something goes wrong during the upgrade process.
Upgrading Ubuntu via Command Line Interface (CLI)
Step 1: Update Existing Packages
Open your terminal and type the following command:
sudo apt updateThe sudo command allows you to run operations that require administrative or root permissions. The apt update command fetches the package information from all configured sources (websites, local file systems) listed in your system’s /etc/apt/sources.list file.
Next, upgrade the existing packages on your system to their latest versions with the following command:
sudo apt upgrade -yThe -y option is used to automatically answer yes to any prompts that may come up during the upgrade process.
Step 2: Initiate the Release Upgrade
After updating and upgrading your existing packages, initiate the release upgrade process with the following command:
sudo do-release-upgradeThe do-release-upgrade command is a tool that upgrades your system to the latest release. It handles the removal of old packages and the installation of new ones.
Upgrading Ubuntu via Graphical User Interface (GUI)
If you prefer using a GUI over the command line, you can use the Software Updater tool. Here’s how:
Step 1: Open Software Updater
Navigate to the Applications menu and open the Software Updater. It will automatically check for updates and apply them.
Step 2: Initiate the Upgrade
After updating your existing packages, the Software Updater should prompt you about the new release. Follow the on-screen instructions to upgrade your Ubuntu version.
Early Adoption and Testing
While it’s generally recommended to wait for the official release of Ubuntu 22.04 before upgrading, some users may want to upgrade earlier. If you’re one of them, remember to test the new operating system on a virtual machine or a test machine before upgrading your main system.
If you want to upgrade to Ubuntu 22.04 before its official release, you can modify the package sources by running the following command:
sudo sed -i 's/impish/jammy/g' /etc/apt/sources.listThe sed command is a stream editor for filtering and transforming text. The -i option allows in-place editing of the input file. The s/impish/jammy/g expression replaces all instances of ‘impish’ (the codename for Ubuntu 21.10) with ‘jammy’ (the codename for Ubuntu 22.04).
After modifying the package sources, run the update and upgrade commands again, and remember to reboot your system after a successful upgrade.
Conclusion
Upgrading to a new Ubuntu release is a straightforward process, whether you prefer using the command line or a graphical interface. As always, remember to back up your data before starting the upgrade process, and consider testing the new release on a separate system or virtual machine if you’re an early adopter.
For more information and updates on the release process, refer to the official Ubuntu blog or the Ubuntu community forums.
Yes, you can upgrade directly from Ubuntu 21.10 to Ubuntu 22.04 without the need to upgrade to any intermediate versions. The upgrade process will handle all necessary changes and updates.
The duration of the upgrade process can vary depending on various factors such as the speed of your internet connection and the performance of your system. On average, it can take anywhere from 30 minutes to a few hours.
