Most distributions ask you to pick a desktop before you ever boot the installer, and switching later feels like moving house. aerynOS 2026.11, released on 2 November, takes the opposite approach: one independently developed distribution, four full desktop environments to choose from at install time, plus about a dozen Wayland compositors for anyone who would rather build their own. It is the most interesting part of a refresh that is otherwise aimed squarely at early adopters, not at anyone looking for a new daily driver this weekend.

The four desktops, and who each one suits

The new arrival is Budgie 10.10.4, added in collaboration with Budgie lead Joshua Strobl and now offered as an install-time option. Budgie is the traditionalist of the four: a familiar panel-and-menu layout, now fully Wayland-based, that feels immediately at home to anyone coming from a classic desktop. If you want Linux to stay out of your way, start here.

GNOME 51.1 is the live environment on the new ISO, and the sensible default if you have no strong preference. It is clean, opinionated, and consistent, and it is the desktop the project itself puts in front of testers first. KDE Plasma 6.8.2 is the opposite bet: endless customization, widgets, and settings, for users who enjoy tuning every corner of their desktop. COSMIC 1.11, System76's Rust-based desktop, sits between them, with a modern, tiling-friendly workflow and a new COSMIC Viewer app, contributed in part by aerynOS staff working with the System76 team.

That spread is the real story. Most distros ship one flagship desktop and treat the rest as spins. Here, the choice is the feature, and the ISO lets you compare all four on the same underlying system, with the same package manager and kernel, instead of comparing four different distributions and wondering which difference actually mattered.

What else lands in 2026.11

Under the desktops, the ISO ships Linux kernel 7.2.14, with the 6.18.60 LTS kernel also available in the repositories, plus Mesa 26.2.6, Firefox 159, PipeWire 1.6.11, and Wine 11.21. A smaller but practical addition is fwupd, so early adopters on supported hardware can handle firmware updates through the Linux Vendor Firmware Service instead of hunting for vendor utilities.

Two tooling changes matter more than they first appear. The package manager, moss, has a restructured command line built around the project's system-model idea: repositories are managed with moss repo commands and packages with moss package commands, and moss sync -u updates and applies the model. The project calls this a breaking change, made deliberately while aerynOS is still in development, so anyone following older moss guides will need to relearn the verbs. And the ISO carries two installers: the existing lichen installer, and a new lichen-installer (run as lichen-tui) that handles partitioning itself, supports Btrfs root partitions with a separate @home subvolume, and carries Wi-Fi and keyboard settings into the installed system.

The honest caveat, before you install anything

Read the project's own framing before reaching for a USB stick: aerynOS is still in development, and the new installer is explicitly not daily-driver ready. It does not yet support disk encryption or dual booting, and the team says so plainly. That rules out two common setups outright. If you dual boot, our dual-boot guide is still the right reference for a stable distribution, but it is not a workaround for this ISO: use the existing installer in a virtual machine instead, and treat the new installer as something to test and report on, not to trust with real data.

The sensible test plan is short. Boot the ISO in a VM, try the live GNOME environment, then install once with each desktop you are genuinely curious about, or at least the two finalists, and spend a day in each doing ordinary work: browsing, files, settings, and updates through moss. Note which desktop's defaults you stop fighting first. That is usually the right answer, and it is a better test than any feature list, because desktop preference is mostly about friction you notice after the novelty wears off. If you want a reference point for how a polished, single-desktop release feels by comparison, our look at Linux Mint 27 is a useful contrast, and SteamOS 3.9.5 shows what Plasma looks like when it is tuned for one device instead of offered as one of four choices.

aerynOS is not asking to replace your distribution yet. It is asking testers to kick the tires on a genuinely unusual proposition: four mature desktops, one young system underneath, and tooling that is still finding its final shape. For desktop-curious users with a spare VM, that is exactly the right invitation. For everyone else, the 2026.11 ISO is a preview worth watching, and the desktop you pick in it may tell you something useful about the desktop you want everywhere else.
