How To Fix Ubuntu 20.04 Upgrade Issue to 22.04

Ubuntu 7

In this article, we will discuss how to troubleshoot and resolve issues that may arise when upgrading from Ubuntu 20.04 to Ubuntu 22.04. Please note that Ubuntu 22.04 is still in its development phase and is not yet available as a stable release. Therefore, the upgrade path from 20.04 to 22.04 is not officially supported at this time. However, we will provide some general troubleshooting steps that can be helpful for resolving common upgrade issues.

Understanding the Upgrade Process

Before we delve into the troubleshooting steps, it’s important to understand what happens during an Ubuntu upgrade. When you initiate an upgrade, your system checks the Ubuntu servers for a new release. If a new release is found, the system downloads the necessary packages and installs them.

The command sudo do-release-upgrade -d is typically used to upgrade to a development release. The -d flag tells the system to look for development releases. However, this command may not work if the development release is not yet available.

Checking Your Current System

First, let’s check the current settings on your system. Open the /etc/update-manager/release-upgrades file with a text editor. This file controls how the system handles upgrades. The Prompt line should be set to normal if you want to upgrade to every new release, or lts if you only want to upgrade to new LTS (Long Term Support) releases.

sudo nano /etc/update-manager/release-upgrades

If the Prompt line is not set to your desired value, change it and save the file.

Updating Your System

Before attempting an upgrade, it’s always a good idea to update your current system. This can be done with the following commands:

sudo apt update
sudo apt upgrade

The apt update command updates the list of available packages from the Ubuntu servers. The apt upgrade command installs the latest versions of the packages currently installed on your system.

Attempting the Upgrade

Once your system is updated, you can attempt the upgrade with the do-release-upgrade command:

sudo do-release-upgrade

If the upgrade is still not available, you may need to wait until the official release of Ubuntu 22.04.

Troubleshooting Upgrade Issues

If you encounter issues during the upgrade process, there are several steps you can take to troubleshoot:

  • Check the /var/log/dist-upgrade directory for log files that may provide clues about what went wrong.
  • If you encounter package conflicts, you can try resolving them manually with the apt command.
  • If all else fails, you may need to consider a fresh install of Ubuntu 22.04 once it is officially released.

Conclusion

Upgrading to a new Ubuntu release can sometimes be a complex process, especially when the new release is still in development. By understanding the upgrade process and knowing how to troubleshoot common issues, you can ensure a smoother transition to the new version. Always remember to backup your data before performing an upgrade, and don’t hesitate to seek help from the Ubuntu community if you encounter difficulties.
