(DEBIAN ONLY): If you would like to upgrade to the latest Kernel (AGGRESSIVE UPGRADE), follow the commands below:
> **Warning**
> The latest Kernel that Debian officially supports is available in the `unstable release`. Debian Unstable (also known by its codename "Sid") is not strictly a release, but rather a rolling development version of the Debian distribution containing the latest packages that have been introduced into Debian. Upgrading to the latest Kernel might potentially introduce breaking changes to your system, so please do at your own risk.
Reference: [https://www.itsfoss.net/installing-linux-5-14-kernel-on-debian-11/](https://www.itsfoss.net/installing-linux-5-14-kernel-on-debian-11/)
> **Note**
> Please modify the following line if your system is NOT on Debian11: `Pin: release a=bullseye` - e.g. `Pin: release a=buster` (Debian10)
```shell
# Sync databases.
sudo apt update
# Add unstable source
cat <<EOF | sudo tee -a /etc/apt/sources.list/
deb http://deb.debian.org/debian unstable main contrib non-free
deb-src http://deb.debian.org/debian unstable main contrib non-free
EOF
# Create apt preferences
cat <<EOF | sudo tee /etc/apt/preferences
Package: *
Pin: release a=bullseye
Pin-Priority: 500
Package: linux-image-amd64
Pin: release a=unstable
Pin-Priority: 1000
Package: *
Pin: release a=unstable
Pin-Priority: 100
EOF
# Perform full dist-upgrade
sudo apt dist-upgrade
```
Reboot to take effect:
```shell
sudo reboot
uname -r
```
