Tobias Heider has written an article that explains changes that are coming for Ubuntu's generic Arm64 desktop ISO images in the 25.10 release. The current solution, Heider says, depends on GRUB features that are unavailable in secure boot mode and require adding device-specific logic to multiple packages. The new solution, called stubble, is derived from systemd-stub:

A bundled stubble image contains stubble itself, a Linux kernel, a HWID lookup table to map devices to device trees and multiple device trees. When grub loads this "kernel", stubble executes first, reads the SMBIOS table to generate HWIDs, looks for a match in the embeeded lookup table and loads a matching device tree before passing control to the actual Linux kernel.

The elegance in this approach lies in how it interacts with the rest of the system. Integrating stubble happens entirely at build time in the kernel package. The stubble package is a build dependency for the kernel. After building the kernel itself, we bundle it with stubble and our DTBs and ship the combined binary instead. The resulting stubble + kernel + dtb bundle can be loaded by grub like any other Ubuntu kernel. No further changes in grub or other packages are necessary to make it work.

Greg Kroah-Hartman has announced the release of the 6.16.2, 6.15.11, and 6.12.43 stable kernels. He notes that this is the last release in the 6.15.y series, and recommends that users move to the 6.16.y kernel branch at this time.

Ken Jin welcomed EuroPython 2025 attendees to his talk entitled "Building a new tail-calling interpreter for Python", but noted that the title really should be: "Measuring the performance of compilers and interpreters is really hard". Jin's efforts to switch the CPython interpreter to use tail calls, which can be optimized as regular jumps, initially seemed to produce an almost miraculous performance improvement. As his modified title suggests, the actual improvement was rather smaller; there is still some performance improvement and there are other benefits from the change.

After more than two years of development, the Debian Project has released its new stable version, Debian 13 ("trixie"). The release comes with the usual bounty of upgraded packages and more than 14,000 new packages; it also debuts Advanced Package Tool (APT) 3.0 as the default package manager and makes 64-bit RISC-V a supported architecture. There are few surprises with trixie, which is exactly what many Linux users are hoping for—a free operating system that just works as expected.
