If you are currently using Ubuntu 24.10 and are eager to upgrade to the new Ubuntu 25.04 release, the process is straightforward. There’s no need to download an ISO or perform a clean installation if you have a working internet connection and your system is fully updated.
It’s advisable to upgrade soon, as support for Ubuntu 24.10 will end in July. Users who do not upgrade will miss out on critical security updates. For those who prefer to avoid frequent upgrades, installing Ubuntu 24.04 LTS, which is supported until 2029, might be a better option.
Requirements for the Upgrade
To initiate the upgrade to Ubuntu 25.04, ensure you meet the following criteria:
- Running Ubuntu 24.10 (not older versions like 24.04 or 23.10)
- Installed all pending updates
- Have a stable internet connection (the upgrade requires downloading numerous packages)
Allocate enough disk space for the upgrade; the assistant will verify this and halt the process if space is insufficient. It is also recommended to back up any important files or settings before starting the upgrade, as issues can arise.
How to Upgrade
To start the upgrade process:
- Wait for the upgrade notification from Ubuntu.
- Use the Software Updater app to initiate the upgrade.
Both methods utilize the same graphical interface to manage the upgrade.
Follow the on-screen instructions. Initially, you’ll review release notes and known issues. Once comfortable, you’ll see a list of packages to be updated, removed, or installed. Confirm your agreement to start the upgrade.
During the upgrade, you may encounter prompts asking for confirmations regarding package replacements or restarts. Pay close attention to these to ensure a smooth process.
Once everything is completed, you will be prompted to restart your system. It’s essential to reboot immediately to finalize the upgrade and experience all new features.
Command Line Upgrade Option
If you prefer using the command line, you can upgrade by running the following command in a terminal:
sudo do-release-upgradeThis command will check for the new release and prompt you for confirmation to proceed. After that, follow the visual prompts to complete the upgrade process.
Upgrade Tips
- You can continue to use Ubuntu during the upgrade; however, issues might arise. It’s best to allow the process to finish without interruption.
- Do not leave your device unattended, as you will need to respond to prompts during the upgrade.
- For laptop users, ensure your device is plugged into power during the upgrade to prevent any disruptions.
Important Note: Upgrading directly from Ubuntu 24.04 LTS to 25.04 is not possible. You would need to first upgrade to Ubuntu 24.10 before proceeding to 25.04. Alternatively, a fresh install using the new ISO might be simpler.
