Upgrading your Linux Mint operating system is an essential task to keep your system secure, up-to-date, and equipped with the latest features. If you’re using Linux Mint 21.3 and wish to upgrade to the next version, Linux Mint 22, this comprehensive guide will walk you through the entire process. Let’s dive into the step-by-step process of upgrading Linux Mint 21.3 to Linux Mint 22.

Before proceeding with the upgrade, it’s important to back up your system, ensure compatibility, and follow a structured approach to avoid potential issues. In this article, we will cover the preparation steps, the upgrade process, and some troubleshooting tips.

Preparation Before Upgrading Linux Mint

Upgrading your operating system can be straightforward, but there are a few key things to prepare to make sure the process goes smoothly. Following these preparatory steps will save you from headaches later on.

Backing Up Your Important Data

Before making any major changes to your system, especially an OS upgrade, it’s crucial to back up your data. While the upgrade process is generally safe, there’s always a small risk that something could go wrong, potentially leading to data loss. Here’s how to safely back up your data:

• Backup Personal Files – Use external storage devices (like an external hard drive or USB flash drive) to back up essential files, such as documents, media, and configuration files.
• Backup System Settings – Linux Mint provides a built-in tool called “Timeshift” that allows you to create system snapshots. Timeshift will let you restore the system to a previous state in case something goes wrong during the upgrade process.
  • Open Timeshift from the menu and follow the on-screen instructions to create a snapshot.
  • Store the snapshot on an external storage device if possible.

Check for System Compatibility

Upgrading from Linux Mint 21.3 to Linux Mint 22 may bring new features, but it also comes with new system requirements. Although Linux Mint generally remains lightweight and efficient, newer versions may require better hardware or have changes in driver support.

• Check Hardware Requirements – Compare your system’s specs (CPU, RAM, disk space, etc.) with the minimum requirements of Linux Mint 22. For most modern systems, this shouldn’t be a concern, but it’s still good to verify.
• Update Installed Packages – Before starting the upgrade, it’s essential to ensure all installed software is up-to-date. To do this, open a terminal and run the following commands:

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade

• Purge Unnecessary Packages – Removing unnecessary packages can help prevent potential conflicts during the upgrade. Use the following command to remove any unneeded packages:

sudo apt autoremove

Enable Recommended Repositories

For a smooth upgrade, make sure you have enabled the necessary repositories:

• Open the Update Manager.
• Go to Edit > Software Sources.
• Under the Linux Mint Base section, make sure that the appropriate repositories are selected, including the ones for Linux Mint 22 (if available).
• You should also ensure that your Main and Base mirrors are up-to-date and fast for your region.

You may be prompted to install the Mint Upgrade tool if you haven’t done so already. Run the following command in a terminal to install the tool:

sudo apt install mintupgrade

Step 3: Simulate the Upgrade Process

Before proceeding with the actual upgrade, it’s a good idea to simulate the upgrade process to ensure everything will work properly. To do this, open the terminal and run:

sudo mintupgrade check

This command will check for potential issues, such as broken packages, dependency conflicts, or unsupported software. If any problems are found, the tool will provide recommendations on how to resolve them.

Step 4: Download the Upgrade Packages

Once the simulation is complete and you’re confident the upgrade will proceed without issues, you can download the upgrade packages by running:

sudo mintupgrade download

This command will download all the necessary packages for the upgrade to Linux Mint 22.

Step 5: Apply the Upgrade

After the download is complete, it’s time to apply the upgrade. This step will install the downloaded packages and upgrade your systemLinux Mint 21.3 to Linux Mint 22. Run the following command:

sudo mintupgrade upgrade

The upgrade process will begin. Depending on your internet speed and system performance, the upgrade might take a while to complete.

Step 6: Reboot the System

Once the upgrade is finished, reboot your system to apply the changes. You should now be running Linux Mint 22.

sudo reboot

Method 2: Upgrading Via the Terminal (Command Line Method)

If you prefer to upgrade Linux Mint using the terminal, you can follow these steps. The command-line method is slightly more technical but provides more control over the upgrade process.

Step 1: Update and Upgrade Your Current System

Before starting the upgrade, make sure your current system is fully updated. Open a terminal and run:

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade

This ensures that all installed packages are up-to-date.

To upgrade from Linux Mint 21.3 to Linux Mint 22, you need to modify your repository sources to point to the new version. You can do this by manually editing the sources list.

• Open the sources list file in a text editor:

sudo nano /etc/apt/sources.list

Find all entries that mention vanessa (the codename for Linux Mint 21.3) and change them to vera (the codename for Linux Mint 22). The repositories should look like this:

deb http://packages.linuxmint.com vera main upstream import backport
deb http://archive.ubuntu.com/ubuntu focal main restricted universe multiverse

• Save the changes and exit the text editor by pressing Ctrl + X, then Y, and then Enter.

Step 3: Update Package Sources and Upgrade

After editing the repository list, you need to update the package sources and upgrade your system from Linux Mint 21.3 to Linux Mint 22. Run the following commands:
