**Important Note**
Installing a custom kernel like Xanmod carries potential risks, and it may make your system unstable or unusable. Make sure to back up your important data before proceeding. If you are not comfortable with kernel manipulations, it's best not to continue with this procedure.
Steps from https://xanmod.org/#apt_repository:
**1. Register the PGP key**
```sh
wget -qO - https://dl.xanmod.org/archive.key | sudo gpg --dearmor -o /usr/share/keyrings/xanmod-archive-keyring.gpg
```
**2. Add the repository**
```sh
echo 'deb [signed-by=/usr/share/keyrings/xanmod-archive-keyring.gpg] http://deb.xanmod.org releases main' | sudo tee /etc/apt/sources.list.d/xanmod-release.list
```
**3. Then update and install**
```sh
sudo apt update
sudo apt install linux-xanmod-x64v3
```
**4. Reboot**
