What's New in Ubuntu 26.10 "Stonking Stingray" — and Should You Upgrade Your Server?
Ubuntu 26.10, codenamed Stonking Stingray, is Canonical's 45th Ubuntu release, and it arrived on 15 October 2026 as an interim release with nine months of support. The headline changes are Linux kernel 7.3, the GNOME 51 desktop, and a complete move to Rust-based core utilities, plus a long list of newer server packages. This guide covers what's new in Ubuntu 26.10, what it changes for your server, and whether you should upgrade, as of November 2026.
If you run Ubuntu on a VPS, the short answer is in the support window, not the feature list: 26.10 is supported until July 2027, while Ubuntu 26.04 LTS is supported until 2031. Read our VPS hosting guide first if you are still choosing the server this release would run on, then use the sections below to decide whether Stonking Stingray earns a place on it.
What Is New in Ubuntu 26.10?
Ubuntu 26.10 is an interim Ubuntu release that ships Linux kernel 7.3, the GNOME 51 desktop, 100% Rust-based core utilities, post-quantum package signing with Sequoia PGP, and OpenSSL 4, with server packages including MySQL 9.7, Postfix 3.11.7, and Samba 4.24.7. It is supported for nine months, until July 2027, and it is the next release after Ubuntu 26.04 LTS. The release is aimed at users who want the newest packages now, not at servers that need years of stability.
Three changes define this release. First, the core utilities your shell uses every day, including cp, mv, and rm, now run on the Rust-based uutils implementation instead of GNU coreutils.
Second, package signing moves toward post-quantum cryptography through Sequoia PGP. Third, the kernel jumps to the 7.3 series, which brings support for the newest Intel, AMD, and NVIDIA hardware.
The rest of this guide walks through each change in turn: the kernel, the desktop, the under-the-hood work, and the server packages. Then it answers the question that matters most for a server owner: should you upgrade, and if so, how?
| Change | What it is | Who it matters to |
|---|---|---|
| Kernel 7.3 | Newest hardware support, including Intel Xe3P and AMD Zen 6 | Desktop users and new servers |
| GNOME 51 | The new desktop release, with a tiling popup and a unified App Center | Desktop users |
| Rust coreutils | cp, mv, and rm now run on Rust (uutils 0.12.0) | Everyone |
| Sequoia PGP | Post-quantum package signing in the main archive | Security-conscious users |
| OpenSSL 4.0.3 | Encrypted Client Hello, expanded QUIC, post-quantum work | Servers and developers |
| MySQL 9.7 LTS | Up from MySQL 8.4, with the old password plugin removed | Database servers |
| OpenSSH 10.5 split | Split into openssh and openssh-gssapi packages | Anyone who logs in over SSH |
| dbus-broker | Replaces dbus-daemon for the system and session buses | Everyone, invisibly |
When Was Ubuntu 26.10 Released, and How Long Is It Supported?
The Ubuntu 26.10 release date was 15 October 2026, and the release is supported for nine months, until July 2027. The exact end date is 15 July 2027, according to the Launchpad release milestone and the support data on an installed system, while the official release notes give the month only. Ubuntu 26.10 is an interim release, which means it sits between long-term support releases and is not a long-term support release itself.
Interim releases never get Ubuntu Pro or Extended Security Maintenance, so there is no paid way to extend 26.10 past July 2027. When support ends, the only supported move is to upgrade to the next release, Ubuntu 27.04, which is dated 22 April 2027. That nine-month clock is the single most important fact in this guide, and it shapes every recommendation below.
What Is New in the Ubuntu 26.10 Kernel?
Ubuntu 26.10 ships Linux kernel 7.3, but the kernel on the release images is version 7.3.0-9.9, built from the upstream 7.3 release candidate 6, because the final upstream 7.3 release landed a few days after Ubuntu's release date. Installed systems receive the finished 7.3 kernel through normal updates, so the release-candidate base is a detail of the install images rather than a permanent state. The official release notes state the kernel version plainly, and the detail matters only if you check the version on a fresh install before updating.
Kernel 7.3 brings hardware enablement for the latest silicon: Intel Xe3P (Nova Lake), AMD Zen 6, and NVIDIA 615 graphics. It also adds early support for Snapdragon X2 Elite laptops, including the Asus Zenbook A14, the HP EliteBook X G2q 14 AI, and the Lenovo Yoga Slim 7x Gen 11, plus more Snapdragon X Elite and X Plus devices. On the server side, the practical change is modest: the amd64 and arm64 kernels now ship software bills of materials under /usr/lib/linux, and prebuilt out-of-tree modules include ZFS 2.4.4.
NVIDIA driver support splits in two in this release. Prebuilt modules ship for the 580 and 615 driver series, and the 615 series ships only open kernel modules, for Turing and newer GPUs, while the 580 series still offers both proprietary and open modules. GNOME 51 also drops the legacy NVIDIA driver interfaces, so older proprietary driver paths stop working here.
What Is New on the Ubuntu 26.10 Desktop?
Ubuntu 26.10 ships GNOME 51, codenamed "A Coruña", with GNOME Shell reporting version 51.0. The release notes describe a smoother, more responsive desktop with frame-scheduling improvements that keep animations smooth under load, plus monitor brightness remembered across reboots and better center-aligned monitor snapping. A new window-tiling popup appears when you drag a window, offering layout choices without a settings toggle to disable it yet.
The App Center now shows a unified view of Snap and Debian package details, with a dedicated Drivers page that lists NVIDIA driver branches. Settings can now show whether the computer is Ubuntu Certified, and fingerprint enrollment has an improved interface. One removal to know about: WEP Wi-Fi configuration is gone from Settings, because the protocol is obsolete and insecure.
Myna, a speech-to-text preview, debuts in 26.10 as an opt-in feature that is not preinstalled. You hold a configurable key to dictate into the focused application, and transcription runs locally on your machine, with no audio sent to a network service. Canonical describes it as an early preview that will keep changing before it becomes a stable, default feature.
TPM-backed full disk encryption no longer needs a hardware root of trust: it is now installable provided a PIN or passphrase is also set on the TPM-backed key. Linuxstans also reports optimized amd64v3 images built alongside the standard ones, though the official release notes do not mention them.
What Changed Under the Hood in Ubuntu 26.10?
The biggest under-the-hood change is the completed move to Rust core utilities: every default core utility, including cp, mv, and rm, now runs on the Rust-based uutils implementation, version 0.12.0. GNU coreutils are still installable if you need them, but the default system no longer uses them. The migration began in Ubuntu 25.10, and 26.04 LTS deliberately kept GNU coreutils, so 26.10 is the first release where the switch is complete.
D-Bus is now provided by dbus-broker, which replaces dbus-daemon for the system and session buses. The new implementation is asynchronous and event-driven, with stricter per-application message accounting. Most users will never notice the change directly, but it is part of the same hardening direction as the Rust core utilities.
Sequoia PGP, a Rust OpenPGP implementation, joins the main archive with the sq and sqv tools as counterparts to gpg and gpgv. Ubuntu 26.10 uses it for post-quantum-ready APT package signing, and the stated goal is for Sequoia to become the default OpenPGP toolchain over time. The older gpg and gpgv tools remain available in main for now.
OpenSSL jumps to version 4.0.3, which adds Encrypted Client Hello, expanded QUIC support, and continued post-quantum improvements, alongside an API and architectural cleanup. Systemd is updated to version 261, and legacy System V script support through systemd-sysv-generator is removed. The developer toolchain ships GCC 15.2.0, Python 3.14.7, Rust 1.97.1, Go 1.27, .NET 10, and LLVM 22.1.8 according to the release-notes toolchain table.
What Changed for Servers in Ubuntu 26.10?
Ubuntu 26.10 refreshes the server stack across the board, and the changes that matter most are MySQL 9.7, the OpenSSH split, and the Postfix and Samba updates. The table below lists the server packages with their 26.10 versions, taken from the official release notes.
| Package | Version in 26.10 | What changed |
|---|---|---|
| Postfix | 3.11.7 | postconf, postalias, postmap, and postmulti support JSON output; BerkeleyDB hash: and btree: maps deprecated |
| Samba | 4.24.7 | New AD audit-logging classes; Entra ID password reset and Keycloak support; AES encryption types by default |
| MySQL | 9.7 LTS | Hypergraph Optimizer and JSON Duality Views; mysql_native_password removed, and the upgrader blocks upgrades until accounts move to caching_sha2_password |
| Valkey | 9.1 | Performance and security threat-model improvements |
| HAProxy | 3.4.2 | Default load-balancing algorithm changed from roundrobin to random; thread count no longer capped at 64 |
| OpenSSH | 10.5 | Split into openssh (no GSSAPI or Kerberos) and openssh-gssapi; fresh installs default to the non-GSSAPI binaries |
| Apache | 2.4.68 | Mostly security fixes across about 25 CVEs; rebuilt against OpenSSL 4 |
| nginx | 1.30.4 | The version in the 26 October 2026 security update, fixing five vulnerabilities including an HTTP/3 data-injection issue |
| PHP | 8.5.9 | Bugfix and security point releases; rebuilt against OpenSSL 4 |
| cloud-init | 26.2 | Sandboxed Jinja template rendering and network improvements |
MySQL 9.7 is the change most likely to bite a server owner. The mysql_native_password authentication plugin was removed upstream, so the release upgrader blocks the upgrade until every account is migrated to caching_sha2_password. Check your MySQL users before you plan an upgrade, not after it fails halfway through.
The OpenSSH split is the second change to plan around. Fresh installs default to the non-GSSAPI binaries, and the upgrader automatically selects the -gssapi variants if it detects GSSAPI use, but the two variants conflict with each other. If your servers log in with Kerberos, confirm the gssapi package is the one installed after the upgrade.
HAProxy's default load-balancing algorithm changed from roundrobin to random, using a power-of-two-choices method. That is a behavior change, not just a version bump, so check your HAProxy configuration if you rely on round-robin ordering. If your web stack runs on nginx, our Nginx beginner guide walks through the server setup this release would sit on.
Ubuntu 26.10 vs 26.04 LTS: The Honest Comparison
Ubuntu 26.10 and Ubuntu 26.04 LTS are different kinds of release, and the comparison that matters is support length, not feature count. Ubuntu 26.04 LTS, codenamed Resolute Raccoon, was released on 23 April 2026 and is supported until 2031, while 26.10 is supported for nine months, until July 2027. Every feature 26.10 adds is something 26.04 will either receive later or that the next LTS, 28.04, will stabilize.
| Aspect | Ubuntu 26.10 Stonking Stingray | Ubuntu 26.04 LTS Resolute Raccoon |
|---|---|---|
| Release date | 15 October 2026 | 23 April 2026 |
| Type | Interim | Long-term support |
| Support ends | July 2027 (15 July 2027) | 2031 |
| Kernel | 7.3 | 7.0 series |
| Desktop | GNOME 51 | GNOME 50 |
| Core utilities | 100% Rust uutils | GNU coreutils |
| OpenPGP | Sequoia sq and sqv in main, alongside gpg | GnuPG only |
| OpenSSL | 4.0.3 | 3.5.5 |
| MySQL | 9.7 LTS | 8.4 LTS |
| RISC-V desktop | Official images (SpacemiT K3, SiFive BigSky) | No official desktop image |
| D-Bus | dbus-broker | dbus-daemon |
| Next release | 27.04 (April 2027) | 26.10 |
The table shows why the two releases serve different users. A desktop user who wants the newest GNOME and kernel gets a real upgrade from 26.10, while a server owner gets newer packages at the cost of a nine-month support window. The LTS release keeps GNU coreutils and GnuPG deliberately, because stability matters more than novelty on a long-lived system.
Should You Upgrade to Ubuntu 26.10?
For a production server, no: stay on Ubuntu 26.04 LTS and let 26.10 be a test system. For a desktop, a lab machine, or a test VPS, yes, if you want the newest kernel, GNOME 51, and server packages months before the next LTS. The deciding factor is the support window, and the arithmetic below makes the gap concrete.
from datetime import date
release = date(2026, 10, 15)
support_end = date(2027, 7, 15)
lts_end = date(2031, 5, 1)
next_release = date(2027, 4, 22)
support_days = (support_end - release).days
lts_days = (lts_end - release).days
gap_days = (next_release - release).days
print("26.10 support window:", support_days, "days")
print("26.10 release to LTS end:", lts_days, "days")
print("LTS window is about", round(lts_days / support_days, 1), "x the interim window")
print("Days from 26.10 to 27.04:", gap_days)
print("Upgrades to reach 28.04 LTS: 26.10 -> 27.04 -> 27.10 -> 28.04 =", 3)
The numbers say it plainly. Ubuntu 26.10 gives you 273 days of support, and from its release day to the end of LTS support in May 2031 is 1,659 days, which is about 6.1 times longer.
Upgrading to 26.10 also commits you to the interim treadmill: 27.04 arrives 189 days after 26.10, and reaching the next LTS means three upgrades in a row, from 26.10 to 27.04 to 27.10 to 28.04 LTS. A server that exists to stay up does not want three major upgrades in eighteen months.
There is one good reason to run 26.10 on a server: testing. Ubuntu 26.10 previews what the next LTS will stabilize, so a staging server on 26.10 finds the configuration problems, package changes, and third-party repository gaps months before they reach production. Run it beside your LTS fleet, not instead of it.
| Your situation | Verdict | Why |
|---|---|---|
| Production server | Stay on 26.04 LTS | Nine months of support is too short for a server that must stay up |
| Desktop or laptop | Upgrade if you like | GNOME 51, kernel 7.3, and the newest hardware support are real gains |
| Test or staging VPS | Upgrade | Find the MySQL, OpenSSH, and repository problems before production does |
| New server, fresh install | Install 26.04 LTS | Five years of support beats nine months, even with older packages |
| Developer workstation | Upgrade if you like | The newest toolchain (GCC 15.2, Python 3.14, Rust 1.97) is the point |
How Do You Upgrade to Ubuntu 26.10?
You upgrade with do-release-upgrade, but as of 6 November 2026 the standard upgrade path from 26.04 LTS still appears not open in the stable channel: Stonking Stingray is absent from Ubuntu's stable meta-release file, while the development file now lists it as supported. The status is moving, so check the meta-release file before you start, and do not force the upgrade with the development flag on a machine you care about.
- Back up the system, and confirm you can restore from that backup before you touch anything.
- On a desktop, open Software and Updates and set "Notify me of a new Ubuntu version" to "For any new version", because the default LTS setting only offers long-term support releases.
- On a server, run sudo apt update and sudo apt full-upgrade, then sudo do-release-upgrade, and follow the prompts.
- After the upgrade, confirm the MySQL accounts, the OpenSSH package variant, and every third-party repository before you call the system done.
- Plan the next upgrade now: 27.04 arrives in April 2027, and 26.10 stops receiving updates in July 2027.
Two groups cannot upgrade yet at all. Systems with TPM-backed full disk encryption cannot upgrade from 26.04 LTS to 26.10, and Canonical expects to enable those upgrades during the 26.10 lifecycle. The upgrader also blocks the upgrade while any MySQL account still uses mysql_native_password, which was removed upstream.
What Should You Check Before You Upgrade?
Check every third-party repository before you upgrade, because repositories are keyed to the release codename and vendors publish a stonking build on their own schedule. If a repository you depend on has no 26.10 build yet, the upgrade will either disable it or fail, and Docker and HashiCorp repositories are the usual suspects on a server. Our Docker beginner guide covers the container setup that depends on those repositories, so confirm the repository state before you commit to the upgrade.
Check for a dangling /lib32 symlink, which can stop the upgrade at the base-files package, and check for legacy GRUB customizations on TPM-encrypted systems, which can leave a machine unbootable after update-grub. Never purge an openssh package that is in the removed-but-config-files-remain state, because a known bug in 26.10 can break SSH and lock you out of a remote server. If your server is reached over SSH from a fixed address, our static IP guide explains the addressing setup that keeps that access stable.
Finally, confirm your backups, your monitoring, and your rollback plan. An interim release is the wrong place to discover that your backup never worked, and the nine-month support window means any problem you defer becomes an upgrade you must do under pressure.
What Comes After Ubuntu 26.10?
Ubuntu 27.04, codenamed Tenacious T-Rex, is dated 22 April 2027, and it is the next stop for anyone on 26.10. After that comes 27.10, and then Ubuntu 28.04 LTS, which is where the interim line rejoins long-term support. Each interim step lasts about six months, and support for 26.10 ends in July 2027, so there is no version of this story where you install 26.10 and stop thinking about upgrades.
The features that 26.10 previews, including the Rust core utilities, Sequoia package signing, and OpenSSL 4, are the features the next LTS will inherit and stabilize. That is the real role of an interim release: it lets the ecosystem find the rough edges while the LTS stays boring and reliable. Watch 27.04 for the next round of that work, and expect 28.04 LTS to be the release that makes it boring.
The Bottom Line
Ubuntu 26.10 Stonking Stingray is a solid interim release with a genuinely interesting feature list: kernel 7.3, GNOME 51, Rust core utilities, Sequoia post-quantum signing, OpenSSL 4, and a refreshed server stack led by MySQL 9.7. It is the right release for a desktop, a lab, or a test server, and the wrong release for anything that must keep running untouched for years. The nine-month support window is the whole decision.
Keep production on Ubuntu 26.04 LTS, run 26.10 where you can learn from it, and plan the 27.04 upgrade before July 2027 if you install it. CodexFuse does not offer an Ubuntu tool, so this guide is the explainer, and the site's server guides are the practical companion to it.

Frequently Asked Questions
What is new in Ubuntu 26.10?
Ubuntu 26.10 Stonking Stingray ships Linux kernel 7.3, the GNOME 51 desktop, 100% Rust-based core utilities, Sequoia post-quantum package signing, and OpenSSL 4. It was released on 15 October 2026 as an interim release with nine months of support, until July 2027.
Should I upgrade to Ubuntu 26.10?
Upgrade on a desktop, lab machine, or test server if you want the newest packages, but keep production servers on Ubuntu 26.04 LTS. The nine-month support window means 26.10 needs another upgrade by July 2027, while the LTS release is supported until 2031.
How long is Ubuntu 26.10 supported?
Ubuntu 26.10 is supported for nine months, until July 2027, with the exact end date of 15 July 2027 per the Launchpad milestone and installed-system support data. Interim releases do not get Ubuntu Pro or Extended Security Maintenance, so there is no way to extend support past that date.
Can I upgrade directly from Ubuntu 26.04 LTS to 26.10?
Yes in principle, and you must set Software and Updates to notify you about any new version rather than long-term support versions only. Read the upgrade section above first, because the path status and the encryption blocks change while the release is young.
What kernel does Ubuntu 26.10 use?
Ubuntu 26.10 ships Linux kernel 7.3, and the release images carry kernel 7.3.0-9.9, which is based on a late release candidate of upstream 7.3. Installed systems receive the finished 7.3 kernel through normal updates after installation.
