How to Install Linux Kernel 5.12:

The Ubuntu Mainline Kernel Archive provides the new kernel packages via DEB files.

The mainline build kernels do not include any Ubuntu-provided drivers or patches. They are not supported and are not appropriate for production use.

For those prefer using a graphical tool, see this tool to install the latest Kernel.

To manually download the mainline kernel packages for Linux 5.12, go to the link button:

Download Kernel 5.12 (DEB)

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio):

  2. linux-headers-5.12.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  3. linux-modules-5.12.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  4. linux-image-xxx-5.12.0-xxx-generic(/lowlatency)_xxx_amd64.deb

Alternatively you can download and install the kernel binaries via terminal commands ( open terminal via Ctrl+Alt+T):

cd /tmp/

wget -c

wget -c

wget -c

wget -c

sudo dpkg -i *.deb

Once installed, restart your computer and enjoy!
