upgrade ubuntu version on lightsail

1. Backup: Take a snapshot of your Lightsail instance before upgrading.
2. Connect: SSH into your Lightsail instance.
3. Update Packages: Run sudo apt update and sudo apt upgrade -y to update packages.
4. Upgrade to 22.04: Use sudo do-release-upgrade -d to upgrade from Ubuntu 20.04 to 22.04.
5. Future Upgrade to 24.04: Once Ubuntu 24.04 is released, upgrade using the same command.
6. Reboot: Reboot the instance after the upgrade with sudo reboot.
7. Verify: Check the OS version with lsb_release -a to confirm the upgrade.

Considerations for Lightsail:

• Use snapshots for backups.
• Be mindful of performance limitations during the upgrade.
• Check and adjust firewall settings in the Lightsail console post-upgrade.

The process of upgrading Ubuntu on a Lightsail instance is similar to that on an EC2 instance, but with some Lightsail-specific considerations like using snapshots for backup and ensuring that networking and firewall configurations are properly set. Always take a snapshot before starting the upgrade to ensure you can recover if anything goes wrong.

Hi there,

Wanted to provide an alternative upgrade pathway. You can consider transitioning to a new instance using the ubuntu blueprint with the desired version. You can achieve this by creating a snapshot of your existing instance, then creating a new ubuntu instance using blueprint with the desired version. Once you've confirmed the application is setup on the new instance and working as expected, then you can look to deprecate the old one.

Here's a similar question asked previously for reference:
