How to upgrade to Linux Mint 21.3

How to upgrade to Linux Mint 21.3

It is now possible to upgrade Linux Mint 21, 21.1 and 21.2 to version 21.3.

If you’ve been waiting for this we’d like to thank you for your patience.

1. Create a system snapshot

You can use Timeshift to make a system snapshot before the upgrade.

If anything goes wrong, you can easily restore your operating system to its previous state.

Launch Timeshift from the application menu, follow the instructions on the screen to configure it and create a system snapshot.

2. Prepare for the upgrade

If you installed Cinnamon spices (applets, desklets, extensions, themes), upgrade them from the System Settings.

3. Upgrade the operating system

Upgrading to Linux Mint 21.3 is fast and easy.

In the Update Manager, click on the Refresh button to check for any new version of mintupdate or mint-upgrade-info. If there are updates for these packages, apply them.

Launch the System Upgrade by clicking on “Edit->Upgrade to Linux Mint 21.3 Virginia”.

Follow the instructions on the screen.

If asked whether to keep or replace configuration files, choose to replace them.

4. Change artwork (optional)

Linux Mint 21.3 features artwork changes.

We recommend you reboot your computer for all changes to properly apply.

To select a theme launch the “Themes” settings. The 20.2 look is available under the name “Mint-L”.

5. Reboot the computer

Once the upgrade is finished, reboot your computer.

Commonly asked questions

  • If the upgrade is not available to you, check that you have the latest version of mint-upgrade-info (1.2.5 or higher) and restart the Update Manager by launching it again from the applications menu.
  • If the latest version of mint-upgrade-info is not yet available in your mirror, switch to the default repositories.
  • This happens rarely, but if you ever got locked and were unable to log back in, switch to console with CTRL+ALT+F2, log in, and type “killall cinnamon-screensaver” (or “killall mate-screensaver” in MATE). Use CTRL+ALT+F7 to get back to your session.
