This guide gives you all the information you need to Upgrade to Linux Mint 21.3 “Virginia” from Linux 21.2, 21.1.

Linux Mint 21.3 “Virginia” is released on January 13, 2024 with enhancements and bug fixes for this point release. If you are running Linux Mint 21.2, here’s how you can upgrade to this latest version.

But before you upgrade, you need to do some housekeeping because major version upgrades always come with a fair amount of risk.

That said, make sure of the following before performing the upgrade.

Before you perform the upgrade, remember the followings:

  • The below steps are for Linux Mint 21.2, 21.1, 21 to 21.3 only.
  • What does this mean? If you are running Linux Mint 20.2 or Linux Mint 20.1, you can not directly upgrade to 21 or 21.3. Instead, you need to perform sudo apt update and sudo apt upgrade to reach 20.3. And then, follow the steps outlined here to reach 21.2.
  • After you reach 21.2, you can follow the below steps.

Things to do before the Upgrade Attempt

  • Open the Update Manager and make sure your system is up to date until Linux Mint 21.2.
  • Use TImeshift to create a system restore point after you apply all the pending updates in the above step. If something happens, you can always restore it to this point in time.
  • Take a backup of all of your home, downloads, documents, pictures and videos folders.
  • (Optional) Disable any third-party PPA that you may have added. You can find those in the System Settings > Software Sources > PPAs or Additional Repositories tabs.
  • (Optional) Prepare a LIVE USB of Linux Mint 21 if you cannot boot it after a failed upgrade. It will help to restore via Timeshift.
  • (Optional) Finally, do a fresh reboot before you follow the steps.
  • Ensure you have a stable internet connection and have around 20 mins+ to give attention to the upgrade process.
