Ubuntu 26.10 Beta "Stonking Stingray" Lands With Linux 7.3 and a Full Rust Coreutils Migration

by Geth Author

Ubuntu's newest beta, codenamed "Stonking Stingray," landed on October 1st, 2026 — a few days behind schedule due to infrastructure issues, but worth the wait. "Stonking" is British slang for something impressively large or excellent, a fitting name for a release that ships several meaningful upgrades.

What's New

The headliner is a complete migration to Rust coreutils via the uutils project. Every standard Unix utility you've long relied on — ls, cp, cat, sort — now runs on a memory-safe Rust implementation by default. For most users this will be invisible; for system security, it's a meaningful shift that eliminates an entire category of memory-safety bugs from the base layer.

Ubuntu 26.10 also ships Linux 7.3 (still in release-candidate phase, but included for beta testing), GNOME 51 — the same desktop that debuted in Fedora 45 with passkey login and offline maps — and Mesa 26.2 for improved graphics driver support. The session bus switches from dbus-daemon to dbus-broker for better performance and reliability. WSL and cloud images are part of the beta cycle as well.

Release Schedule

According to the official release schedule, the Release Candidate lands October 8th, and the final release of Ubuntu 26.10 is set for October 15th, 2026. The Canonical team describes the beta as "reasonably free of showstopper image build or installer bugs" — solid enough to test in a VM, not yet recommended as a daily driver.

Why It Matters

26.10 is an interim release, not an LTS. But it's the last non-LTS before the 28.04 LTS cycle, making it a preview of where Canonical is taking Ubuntu for the next several years. The Rust coreutils landing here as stable defaults signals that the 28.04 LTS will almost certainly ship them to hundreds of millions of users.

If you're on Ubuntu 24.04 LTS or 26.04.1 "Resolute Raccoon," this beta won't touch your system — but it's worth watching. Download the Ubuntu 26.10 beta images and file bugs now if you want to help shape what ships in two weeks.
