Install the required compilers and other tools I suggest that you copy existing config file using the cp command: The task can be overwhelming for a new user. You must also specify which kernel modules (drivers) needed for your system. Configure the Linux kernel features and modulesīefore start building the kernel, one must configure Linux kernel features. If you do not get “ BAD signature” output from the “gpg –verify” command, untar/extract the Linux kernel tarball using the tar command, enter: Gpg: There is no indication that the signature belongs to the owner. Gpg: WARNING: This key is not certified with a trusted signature! Gpg: Good signature from "Linus Torvalds " Gpg: assuming signed data in 'linux-5.16.9.tar' 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-5.16.9.tar' $ xz -d -v linux-5.16.9.tar.xz Verify Linux kernel tartball with pgpįirst grab the PGP signature for linux-5.16.9.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-5.16.9.tar.xz represents Linux kernel version 5.16.9. 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. Install Linux kernel and modules (drivers).The procedure to build (compile) and install the latest Linux kernel from source is as follows: How to compile and install Linux Kernel 5.16.9
