Canonical names Ubuntu 27.04 "Tenacious T-Rex," sets an April 2027 launch
The April 22 interim release takes the letter T and brings the project's first extinct mascot to boot.
Ubuntu 27.04 has a name, and Canonical has handed you a date. "Tenacious T-Rex" is the official moniker for the next interim build, and it lands Thursday, April 22, 2027.
That makes it the 46th Ubuntu release on record, following 26.10 "Stonking Stingray," which went out on October 15, 2026. The letter T had been expected for a while now. Since Noble, each release has climbed the alphabet one step at a time, so everyone had basically already guessed the next one.
The reveal came after weeks of community speculation plus a "Guess the release" campaign on Ubuntu's Discourse forum. It ran from mid-September under the theme letter T, so fans were already tossing out Tiger, Tortoise, and Tapir before Canonical made the final call.
Mark Shuttleworth personally announces every codename. He's held that job since the project's founding. This time the social post simply went: "Hear that roar? ... Make way for Tenacious T-Rex!" Jon Seager, Canonical's VP of engineering and lead release manager, also weighed in.
Fair play to the naming committee. A T-Rex had feeble little arms, sure, but it was still the most terrifying thing to roam the Earth. The prehistoric mascot breaks Ubuntu's "living creature only" tradition, the closest call was 9.04's Jaunty Jackalope, which was mythical rather than extinct.
What 27.04 actually is
For those new to the schedule, 27.04 is an interim release, not a long-term-support build. The distinction matters more than the dinosaur.
Interim releases chase the newest kernel, desktop, and toolchain the moment they drop. Support runs about nine months, ending around January 2028. LTS versions get five years, extendable to a dozen or more with Ubuntu Pro.
Keep in mind that these interim builds are exactly where Canonical stress-tests the stuff that later lands in a supported LTS. Most of 27.04's experiments will filter into the 28.04 LTS that enterprises run for a decade.
Not the longest support window in history. If you set and forget, this is where you'd pause.
The predicted specs
Canonical hasn't published a feature list. So what's coming rests on reasoning, not confirmation.
The desktop is expected to be GNOME 52. GNOME 50 shipped earlier this year and 51 landed in late 2026, so a 52 build due around March 2027 is the natural fit. Expect fresher animations, a tweaked search overlay, and continued tuning of the Yaru theme.
The kernel should settle somewhere in the Linux 7.6 to 7.9 range. 26.10 shipped 7.3, and 26.04 LTS rode in on 7.0. Feature freeze typically falls around February 2027, which points right at that window.
The things that actually ship
Rather than lean on grand new features, 27.04 looks set to stabilize what 26.10 already introduced. dbus-broker is replacing the decades-old dbus-daemon message bus. authd plus Microsoft Entra ID brings enterprise login with password and multi-factor authentication baked in.
Then there's a format-agnostic App Center, unifying deb, snap, and flatpak under one management roof.
You'll also see Myna, aka "Talk-to-type," a local speech-to-text voice dictation built into the desktop. It ships as a removable snap, so you can switch it off entirely if voice menus aren't your thing.
RISC-V desktop support continues along for good measure, keeping RVA23-compatible hardware in line as a first-class target.
Why it's worth watching
As of right now, 27.04 is less about a finished feature set and more about momentum. Canonical's four guiding goals, a solid GNOME platform, reasonable secure defaults, a context-aware desktop leaning on local AI, and tighter identity and encryption work, will shape this build and point toward 28.04. A growing slice of core tooling is also being rewritten in Rust.
The short support window will put some people off. Nine months is a fast turnaround, and it forces a migration before 28.04 drops. But that's the whole point: interim releases buy you testing time without trapping you on stale software.
If you want to track the actual build, watch Canonical's Release Team for exact milestone dates. Alpha builds should show up late this year or early 2027, with the beta landing around March 2027.
For what it's worth, "Tenacious T-Rex" signals where Linux is headed more than it promises anything you can touch today. And it's nice to have a dinosaur along for the ride.
