Edubuntu 26.10: Stonking Stingray
Edubuntu 26.10: Stonking Stingray
In this article
Some Linux releases arrive with a blare of benchmarks. Edubuntu 26.10 arrives with a timetable, a lesson plan and, if you are feeling supportive, a teddy bear (more on that later). Released on 15 October 2026 and codenamed "Stonking Stingray", it is the latest interim offering from the Edubuntu Council: a classroom-minded flavour of Ubuntu that pairs a fresh desktop with tools built for educators, administrators and learners of every age.
This overview covers what the release is, what is genuinely new and how to get it running, drawing only on official project sources.
Meet Edubuntu
Edubuntu is an official flavour of Ubuntu, the popular Linux operating system, aimed squarely at classrooms, students of all ages and wider educational communities. Its home page sums up the spirit with the line "Freedom for every classroom", describing a stable, secure and privacy-conscious option for schools.
Behind that tagline sit four simple promises. There is a huge ecosystem of free educational software to draw on. The system runs happily on older hardware, which means less e-waste and more e-learning. It supports a vast array of languages, in the spirit of Ubuntu itself. And it is free and open-source, so anyone may download it, modify it and make it their own.
The mission is just as plain: a community effort to bring the freedom of the Linux desktop, and the vast library of open-source education software, into the classroom. The project is created by volunteers, and it openly invites newcomers to join in.
It has quite a story, too. Edubuntu was revived with version 23.04 after a nine-year hiatus, and 24.04 became its first long-term support release in a decade. Version 25.10 then celebrated twenty years of the project. Today the Edubuntu Council, made up of Amy and Erich Eickmeyer, steers the ship. This release credits a lively supporting cast: Joshua Peisach for advice on tertiary applications, Aaron Prisk for the website, Jeremy Bicha for GNOME guidance and application suggestions, Jonny Eickmeyer for testing and application selection, and founder Oliver Grawert for continued encouragement.
So where does 26.10 sit in the family? As an interim release, it builds on the foundation of the 26.04 LTS and is supported for nine months, until July 2027. The Council describes it as a great fit for educators and administrators who want the latest desktop technology and are comfortable upgrading at each release. Institutions that prefer long-term stability are pointed towards Edubuntu 26.04 LTS, which is supported until April 2029. DistroWatch's tracking agrees on the July 2027 end of life, and lists GNOME as the default desktop, deb and snap as package formats, APT for package management and LibreOffice as the office suite, all free of charge.
A sensible question for any school technician is "who looks after what?". The Council's answer is refreshingly clear. Edubuntu itself supports the educational and instructional packages it includes, its own utilities (the Edubuntu Installer and Edubuntu Menu) and the GNOME Shell extension it provides, the Alphabetical App Grid. The GNOME desktop environment is maintained by the Ubuntu Desktop team, while most applications come from Debian and are maintained upstream. Bug reports should go through the standard Ubuntu channels.
Inside the Toolkit
This is where the release earns its homework stars, especially if you have ever had to set up thirty near-identical machines before the morning bell.
The foundations. The desktop is GNOME 51, which the Edubuntu announcement credits with the latest improvements in performance, usability and polish. Underneath sits Linux kernel 7.3 for updated hardware support and performance gains. One detail worth knowing: because the final upstream 7.3 release is due after general availability, the kernel in the release images is version 7.3.0-9.9, based on 7.3-rc6, according to the Ubuntu release notes.
Branding gets some attention as well. The GRUB boot menu now identifies the system as Edubuntu, the logo under System, then About has been fixed, and the correct Edubuntu mascot now appears when an installation completes on amd64. That last fix landed after the beta.
A smarter installer. The headline Edubuntu-specific change is Edubuntu Installer 1.1, which gives you finer control over what lands on the machine. The improvements apply across the desktop interfaces (GTK4 and Qt6) and the Cockpit module for web-based remote administration alike.
For newcomers, a metapackage is simply a bundle that pulls in a themed set of software, such as everything for music teaching. Until now you chose the bundle and trusted it. Now each metapackage can be expanded to reveal its individual Depends and Recommends packages, and you can install or remove specific entries directly, with checkbox behaviour that better matches what the APT resolver expects. A new metapackages.json file lets administrators and the project decide which metapackages are shown, and whether each one displays its dependencies. The desktop and Cockpit interfaces share that same configuration, so remote administration behaves exactly like sitting at the machine. Translations have been refreshed for all 21 supported languages, including full localisation of the installer slideshow.
Age-group learning profiles. The big idea behind Edubuntu remains software organised by age group and subject. Four profiles are available: Preschool, Primary or Elementary, Secondary (Middle and High School) and Tertiary (College and University). Administrators can apply defaults system-wide through the Edubuntu Installer and Edubuntu Menu Administration, or override them for particular users, which is handy when one lab serves several year groups.
Behind the profiles sit metapackages you can choose in the installer. There are four age-group bundles named ubuntu-edu-preschool, ubuntu-edu-primary, ubuntu-edu-secondary and ubuntu-edu-tertiary. A teaching bundle, ubuntu-edu-teaching, includes tools such as qxw, Auto Multiple Choice and Foliate. A music bundle, ubuntu-edu-music, brings fmit, gnome-metronome, Minuet, Solfege and Pianobooster. Rounding things off is edubuntu-fonts.
Music with a little code. This release's star newcomer is Sonic Pi, a live-coding music environment now part of the music bundle. It teaches music and programming together in a Python-like environment, combining programming, mathematics and music. Pupils who think they dislike coding sometimes change their minds the first time a loop turns into a beat. Menu Administration also puts Sonic Pi and SuperCollider IDE into the Music folder, and adds GNOME Resources and Font Viewer to the Utilities folder.
Everyday student software. The announcement highlights a few representative applications. Gradebook handles student grade tracking and management in the Primary, Secondary and Tertiary profiles. Paperboy, a GTK4 and Libadwaita news reader updated to version 0.8.1a, supports media literacy and current-affairs discussion in the Secondary and Tertiary profiles. Foliate offers e-book reading for digital textbooks and course materials, again in those two profiles and the teaching bundle. The Alphabetical App Grid keeps the application overview in alphabetical order, with software tucked into subject folders, which doubles as a gentle lesson in cataloguing.
Quiet housekeeping. A few technical tweaks keep things tidy. The minimal and Raspberry Pi desktop images are leaner because memtest86+ is no longer recommended on their seeds. KDE's System Settings is blocked from the minimal desktop, since it does not belong on a GNOME desktop. The Edubuntu metapackages have also been refreshed for the Stonking Stingray archive.
What the Ubuntu base brings. Edubuntu is built on Ubuntu Desktop, and its announcement points readers to the Ubuntu 26.10 release notes for the wider picture. Those notes describe a number of changes that classrooms may appreciate, though the Edubuntu announcement does not itemise which ones appear in its own image, so it is worth confirming in a live session.
On the desktop side, GNOME 51 brings smoother frame scheduling under load, monitors that remember their brightness across reboots, automatic screen rotation and an orientation lock on devices with accelerometers, and a touchpad that switches itself off when a mouse is connected. The Papers document viewer can add visual signatures to documents, although these are annotations and do not cryptographically verify authenticity.
Accessibility has had a proper polish. The Reduced Motion setting reaches more of the desktop, screenshot selections can be adjusted from the keyboard, Orca announcements and app-grid navigation are improved, and a new option disables the focus-ring timeout.
App Center now shows Snap and Debian package details in a single unified view, gains a Drivers page for comparing graphics drivers including NVIDIA branches, and can install the codecs needed for one-time playback when a media file calls for one. Some high-quality codecs are proprietary and are not part of the default installation.
On the security and privacy front, Ubuntu 26.10 adopts the memory-safe, Rust-based Sequoia PGP into its main archive, with sq and sqv as counterparts to gpg and gpgv, which remain available. OpenSSL 4 arrives with Encrypted Client Hello and wider QUIC support. The default core utilities now run entirely on the Rust-based uutils implementation, with cp, mv and rm finally migrated. Computers without a hardware root of trust can be installed with TPM-backed full-disk encryption, provided a PIN or passphrase is also set. Administrators can opt out of anonymous Ubuntu Insights reporting for the entire system, overriding individual opt-ins. Settings can show whether a machine is Ubuntu Certified, and WEP Wi-Fi, an obsolete and insecure standard, is no longer supported there.
There is also Myna, an early speech-to-text preview. Hold a configurable key to dictate into the focused app, with transcription running locally and no audio sent to a network service. It is not preinstalled and may change before a stable release.
Getting Started
Choosing an image. Edubuntu 26.10 is distributed as two kinds of image. The desktop image, edubuntu-26.10-desktop-amd64.iso, is for 64-bit PCs and weighs in at about 6.7 GiB (6,851 MB). It lets you try Edubuntu without changing your computer at all and, if you like it, install it permanently afterwards. The preinstalled desktop image, an arm64+raspi file of about 6.0 GiB compressed as .img.xz, unpacks a ready-made Edubuntu onto a Raspberry Pi. Both come with checksum files and a GPG signature, and the desktop ISO also has BitTorrent and zsync downloads. Do verify what you download before you write it to a USB stick; it takes a minute and saves a great deal of head-scratching.
What your hardware needs. Edubuntu 26.10 has system requirements similar to Ubuntu Desktop 26.10. The announcement asks for a 2 GHz dual-core processor or equivalent, 4 GB of RAM (8 GB recommended), 30 GB of storage for a standard installation or 15 GB for a minimal one, a 1024x768 display, and a USB drive or DVD for installation media. Raspberry Pi 5 users need a minimum 64 GB SD card and bootloader EEPROM version 11 FEB 2025 or later.
Two details deserve a gentle flag. First, the download page still says that at least 1024 MiB of RAM is needed to install, which looks like older wording and clashes with the announcement's 4 GB minimum. Plan around the announcement's figures. Second, the announcement names the Raspberry Pi 5 as the supported board, whereas the download page describes the preinstalled image as suitable for Pi 3, 4, 5, CM4 and Zero 2 W. If you are not using a Pi 5, test before rolling anything out.
Upgrading from an earlier release. Upgrades are supported from Edubuntu 26.04 LTS. Edubuntu 25.10 reached end of life in July 2026, so anyone still on it should hop to 26.04 LTS first. Fully update your current system, then remember that an LTS only offers LTS upgrades by default. To be offered 26.10, open /etc/update-manager/release-upgrades and set Prompt=normal. After that, follow the prompt in Software Updater or run do-release-upgrade from a terminal. Availability can be staged, so some machines will see the prompt later than others. Take a full backup first and make sure you can recover if the upgrade fails.
Known issues. The Edubuntu-specific one is that the Ubuntu welcome app branding does not match Edubuntu, and the team is working on ways to resolve it.
Some upgrades might stop on a dangling /lib32 symlink while installing base-files.
Systems running TPM-backed full-disk encryption cannot upgrade from 26.04 LTS to 26.10 at release, although the Ubuntu team expects to enable this during the 26.10 lifecycle. Running update-grub on such systems after conventional GRUB customisation might also prevent booting.
Some laptops with AMD integrated graphics plus a discrete GPU may freeze the built-in display when panel self-refresh is active, particularly with an external display attached.
Some systems with Intel Wi-Fi 6E AX211 may suffer firmware crashes and dropped connections.
The Showtime video player might not display subtitles.
One more transparency note: at the time of writing, the Ubuntu 26.10 release notes were last updated on 14 October yet still carried a banner describing the release as in development, and their official-flavours list did not include Edubuntu. The Edubuntu announcement itself treats those notes as the reference for known issues, so check back for updates. Individual applications can also have their own upstream known issues, so consult their release notes before filing bug reports.
Finding help and good company. The Edubuntu community lives on Ubuntu Discourse, where there is an Edubuntu category as well as a general Support and Help section. Real-time chat happens in the Matrix room #edubuntu:ubuntu.com, and the project posts updates on Mastodon at @edubuntu@ubuntu.social and on X at @edubuntuproject. Because the project is volunteer-run, the home page encourages anyone who wants to make Edubuntu better to follow the Ubuntu contribution guidance and get stuck in.
Supporting Edubuntu. If you would like to help beyond code and testing, the official merchandise shop supports ongoing development, with commissions from sales going directly to the project. The announcement mentions t-shirts, coffee mugs, hats, teddy bears and more, and the shop itself also lists items such as hoodies, polo shirts and stickers. Erich Eickmeyer manages the store, and the Edubuntu Store link sits right in the website's menu. Your jumper, so to speak, becomes a donation.
Final word. Edubuntu 26.10 is a thoughtful, evolutionary release rather than a flashy one, and that suits classrooms rather well. The smarter installer, the Sonic Pi-powered music corner and the careful age-group tooling show a small volunteer team sweating the details that teachers and administrators actually meet. If you want the freshest Edubuntu and enjoy upgrading each cycle, 26.10 is a tidy choice. If your school prizes calm over novelty, 26.04 LTS remains the steady companion until April 2029. Either way, the lessons here are the same ones open source teaches best: share freely, look closely and keep learning.
