Final answer:
Downgrading Ubuntu 22.04 to 20.04 requires a fresh installation, involving backing up data, creating a bootable USB with the older version, and performing the re-installation process.
Step-by-step explanation:
To downgrade Ubuntu 22.04 to 20.04, you generally need to re-install the older version from scratch. This process involves backing up your data, creating a bootable USB with Ubuntu 20.04, and performing a fresh install. Unfortunately, downgrading is not straightforward like upgrading because packages and system files change significantly between versions, which could result in system instability or loss of data if you try to force a downgrade.
Here are the steps you should follow:
- Back up your data. This step is crucial as the downgrade process will erase all your current data.
- Download the Ubuntu 20.04 ISO file from the official Ubuntu website.
- Make a bootable USB drive with the downloaded ISO file using tools like Rufus or UNetbootin.
- Boot your computer from the bootable USB and choose “Install Ubuntu”.
- Follow the installation instructions, selecting the option to erase the disk and install Ubuntu 20.04, which will remove Ubuntu 22.04 and replace it with Ubuntu 20.04.
After installation, you will need to restore your data from the backup and reinstall any additional software you need.
