Step 1: Update Linux Mint
Before installing the Linux Kernel 6.1, it is crucial to ensure your system is current. This includes updating all packages on your system, which can prevent any conflicts from occurring during installation or upgrading.
sudo apt update
Before proceeding, you have the option to preview the updates that will be made to your system by utilizing a command that lists all available upgrades.
apt list --upgradable
If any updates are present, execute the specified command to begin upgrading.
sudo apt upgrade
Step 2: Install Required Dependencies
The Linux Kernel 6.1 installation necessitates the packages listed below. You can install them by running the command provided.
sudo apt install ca-certificates apt-transport-https software-properties-common lsb-release -y
Step 3: Import TuxInvader PPA
The suggested way to install Linux Kernel 6.1 on Linux Mint is by utilizing the TuxInvader Launchpad PPA. However, it is crucial to be aware that these kernels will be superseded by newer versions from the PPA as the mainline kernels have shorter end-of-life than LTS kernels. Once you add the PPA, you will receive notifications of minor updates and new releases.
If you are new to importing GPG keys from Ubuntu‘s KeyServer, you may encounter an issue where your command line terminal does not create the necessary directories. However, this can be quickly resolved by using a command to create these directories, which will ensure seamless operation when launching PPAs on Launchpad.
sudo gpg --list-keys
gpg: directory '/root/.gnupg' created gpg: keybox '/root/.gnupg/pubring.kbx' created gpg: /root/.gnupg/trustdb.gpg: trustdb created
This step is optional, but if you encounter any problems, you can run the command and repeat the process.
You can obtain the necessary GPG key by executing the command provided below.
sudo gpg --no-default-keyring --keyring /usr/share/keyrings/tuxinvader.gpg --keyserver keyserver.ubuntu.com --recv-keys 3844A6C1C6FD1056
gpg: keybox '/usr/share/keyrings/tuxinvader.gpg' created gpg: key 3844A6C1C6FD1056: public key "Launchpad PPA for tuxinvader" imported gpg: Total number processed: 1 gpg: imported: 1
The next step is to import the repository for your Linux Mint system by running the command provided below. Import with the appropriate command for your specific Linux Mint distribution version.
Option 1: Import Linux Kernel 6.1 Repository for Linux Mint 21.x:
echo 'deb [signed-by=/usr/share/keyrings/tuxinvader.gpg] https://ppa.launchpadcontent.net/tuxinvader/jammy-mainline/ubuntu jammy main' | sudo tee -a /etc/apt/sources.list.d/tuxinvader.list echo 'deb-src [signed-by=/usr/share/keyrings/tuxinvader.gpg] https://ppa.launchpadcontent.net/tuxinvader/jammy-mainline/ubuntu jammy main' | sudo tee -a /etc/apt/sources.list.d/tuxinvader.list
Option 2: Import Linux Kernel 6.1 Repository for Linux Mint 20.x:
echo 'deb [signed-by=/usr/share/keyrings/tuxinvader.gpg] https://ppa.launchpadcontent.net/tuxinvader/lts-mainline/ubuntu focal main' | sudo tee -a /etc/apt/sources.list.d/tuxinvader.list echo 'deb-src [signed-by=/usr/share/keyrings/tuxinvader.gpg] https://ppa.launchpadcontent.net/tuxinvader/lts-mainline/ubuntu focal main' | sudo tee -a /etc/apt/sources.list.d/tuxinvader.list
You can now run a quick update to refresh the new source with the imported repository.
sudo apt update
After importing the PPA and running an update, you may notice that some packages need to be updated. You can now proceed with running an upgrade.
sudo apt upgrade
It is now time to install the Linux Kernel 6.1 generic drivers by executing the below command.
sudo apt-get install linux-generic-6.01
It is important to remember that while the command may appear for version 6.0, it is intended for version 6.1.
After the installation process is finished, it is essential to reboot your system so that the new kernel can be activated.
After signing back into your system, you can run the command below to confirm if the new kernel version is operating.
Additional Commands & Tips
How to Restore Default Kernel
If users experience any issues with the new kernel, such as loss of sound affecting their hardware, they can follow these steps to restore the default kernel.
The first step is removing the TuxInvader LaunchPAD PPA by running the command below.
sudo rm /etc/apt/sources.list.d/tuxinvader.list
After removing the TuxInvader LaunchPAD PPA, it is important to perform an APT update to confirm that the repository has been removed from your system. This will ensure that the package lists for all the repositories you have added to your system are up-to-date.
sudo apt update
Use the command below to remove the current kernel and restore the default. This command will uninstall the current version of the Linux kernel and install the kernel version previously set as default. This will ensure that the system is restored to its original state and that any issues caused by the new kernel will be resolved.
sudo apt autoremove linux-generic-6.* linux-headers-6.* linux-image-unsigned-6.* linux-modules-6.* --purge
Note that you may see a message advising removing the Linux Kernel and making the system unbootable. Select <No> to abort, as this is a warning message to ensure you have a kernel installed before reboot, which will be covered shortly.
Before rebooting, confirming the default generic version is installed important. Do not worry too much about this step, as alternative versions can be installed later. The main goal is to get your system back to its working order.
For Linux Mint 21.x users, use the following command:
sudo apt install --install-recommends linux-generic-hwe-22.04
For Linux Mint 20.x users, use the following command:
sudo apt install --install-recommends linux-generic-hwe-20.04
It is normal to see an output message indicating that the Linux Kernel is already installed. The commands are designed to ensure that a Linux Kernel is on your system, preventing potential rebooting issues.
You can now reboot your Linux Mint system by using the command provided below or, for desktop users who prefer, use the GUI restart option.
At this stage, verifying that the default generic kernel is successfully installed is important.
sudo uname -r
Your system should be back to the standard, generic Linux Kernel that was present before upgrading. You can maintain this version, investigate different Linux Kernels like Liquorix and XanMod, or even create your own Linux Kernel if the TuxInvader PPA does not meet your needs.
Installing the latest Linux Kernel 6.1 on a Linux Mint system can provide many advantages, such as enhanced performance, security, and new features. The TuxInvader Launchpad PPA makes installing the kernel on Linux Mint 21 or 20 desktops or servers straightforward. By adhering to the steps outlined in this guide, you can import the PPA and install Linux Kernel 6.1 using the command line terminal. It’s essential to remember that updating your kernel can cause compatibility issues with some software, so it’s always advisable to back up your data before proceeding with any update. Overall, installing the latest Linux Kernel 6.1 on the Linux Mint system is a relatively straightforward process that can bring many benefits to your system.
