RSA key ID 79BE3E4300411886 (from the above outputs): Grab the public key from the PGP keyserver in order to verify the signature i.e. Gpg: Can't check signature: No public key Sample outputs: gpg: assuming signed data in 'linux-5.4.1.tar' $ xz -d -v linux-5.4.1.tar.xz Verify Linux kernel tartball with pgpįirst grab the PGP signature for linux-5.4.1.tar: You can extract the source code in your $HOME directory or any other directory using the following unzx command or xz command: You really don’t have to extract the source code in /usr/src. Use the wget command to download Linux kernel source code: For example file linux-5.4.1.tar.xz represents Linux kernel version 5.4.1. The filename would be linux-x.y.z.tar.xz, where x.y.z is actual Linux kernel version number. Click on the big yellow button that read as “ Latest Stable Kernel“: Visit the official project site and download the latest source code.

How to compile and install Linux Kernel 5.4.1 However, instructions remain the same for any other Linux distribution. The following instructions successfully tested on an RHEL 7/CentOS 7 (and clones), Debian Linux, Ubuntu Linux and Fedora Linux 28/29. This step by step howto covers compiling Linux kernel version 5.4.1 under an Ubuntu or Debian Linux.
Compiling kernel needs to understand few things and then type a couple of commands. However, new Linux user/admin find it difficult to compile Linux kernel.
