You Can Now Install Linux Kernel 6.13 on Ubuntu, Here’s How
Linux kernel 6.13 was released on January 19th, 2025, with new features like lazy preemption support, user-space shadow stack support for AArch64 (ARM64) via Guarded Control Stack (GCS), support for running Linux in protected virtual machines (a.k.a. realm) under the Arm CCA (Confidential Compute Architecture), support for 6-node sub-NUMA clustering on Intel, split-lock detection support for AMD CPUs, and much more.
Ubuntu users who need extra hardware support or just want a taste of the new features can now install Linux kernel 6.13. I’ve tested this tutorial on Ubuntu 24.10 (Oracular Oriole) and it worked without issues. Packages are available for 64-bit (x86_64), AArch64 (ARM64), ARMhf, PowerPC 64-bit Little Endian (ppc64el), and IBM System z (s390x) architectures.
