How to Upgrade Linux Mint 21.3 to Linux Mint 22 Safely

Upgrading from Linux Mint 21.3 to 22 brings faster performance, improved hardware support, and enhanced security. This guide explains the upgrade process step by step for a smooth transition.

Why Upgrade to Linux Mint 22

Linux Mint 22, codenamed Wilma, introduces performance boosts, improved HiDPI support, and a more secure Software Manager. With Kernel 6.8, you gain better hardware compatibility, while the switch to PipeWire modernizes the audio stack. The release also enhances fractional scaling for high-resolution displays, introduces power modes for laptops, and adds tools like the Matrix client for community communication.

System Requirements Before You Begin

To upgrade without problems, ensure your system meets the minimum requirements:

• At least 2GB RAM (4GB or more recommended)
• 20GB of free disk space (100GB recommended for smooth use)
• A resolution of 1024×768 or higher

Also, fully update Linux Mint 21.3 and temporarily disable any third-party PPAs. These steps reduce compatibility issues during the upgrade.

For Linux admins, having a list of useful command lines for Linux Admins can make tasks like checking disk space, monitoring processes, or managing packages much faster during upgrades or troubleshooting.

Create Backups and Snapshots

Preparation is critical before major upgrades. Use Timeshift to create a full system snapshot and store it on an external drive. This allows you to restore your setup if something fails. Additionally, back up personal files such as documents, pictures, and videos. Keep notes of custom configurations or installed software so they can be restored later.

Install the Mintupgrade Tool

The upgrade requires the mintupgrade tool. Update your package cache first:

sudo apt update

sudo apt upgrade -y

Then install the tool:

sudo apt install mintupgrade

If the package is missing, you may need to switch to default Linux Mint mirrors. Open Software Sources, select the default Linux Mint and Ubuntu repositories, update the package list, and try again. Disabling PPAs or editing the sources list manually also fixes most installation errors.

Run the Mintupgrade Tool

Once installed, launch the upgrade with:

sudo mintupgrade

The tool guides you through three main phases:

1. Testing Phase – It checks if backups exist, verifies system readiness, and lists all packages to be added, removed, or updated.
2. Downloading Phase – The system fetches all required packages. This step depends on your internet speed and may take time.
3. Upgrade Phase – The tool applies the updates and installs Linux Mint 22. Some fonts or visuals may look broken temporarily, but this resolves after reboot.

Post-Upgrade Cleanup

After a successful upgrade, you should remove unnecessary files:

sudo apt remove mintupgrade

sudo apt autoremove

sudo apt clean

sudo reboot

Rebooting loads your new Linux Mint 22 environment.

Users with modern hardware may notice improved security features, including better integration for TPM Chip in Linux, which enhances encryption, secure boot, and system integrity checks.

Key Features of Linux Mint 22

After upgrading, you will notice several improvements:

• Performance and stability – Faster Software Manager and smoother updates thanks to multithreading.
• Enhanced visuals – Fractional scaling options such as 125% and 150% display better on HiDPI screens.
• PipeWire sound server – A lighter, modern replacement for PulseAudio.
• Security improvements – Verified Flatpak maintainers displayed, with warnings for unverified apps.
• Cinnamon 6.2 desktop – Adds customization improvements and bug fixes.
• Matrix support – Built-in web app for chatting with the open-source community.
• Fresh look – New wallpapers and updated artwork refresh the desktop experience.

Troubleshooting Common Issues

If the upgrade fails or packages break, try the following steps:

• Confirm enough disk space is available.
• Reboot and rerun the upgrade.
• Disable external devices that may cause conflicts.
• Restore your Timeshift snapshot if the system becomes unstable.
