Feel at home
The essentials,
considered together.
A consistent workspace for your files, apps, and settings, with light, dark, and high-contrast choices.
02 / Bring compatible apps
A careful way to add more.
Inspect and import compatible portable DEB, RPM, and Type-2 AppImage files. Lunex 0.8 adds a 600 MiB input limit and the lunex-pkg command.

Reconnect on your terms.
Choose whether to remember a Wi-Fi connection and reconnect after an installed reboot. Saving a network is always optional.
Step away. Lock up.
A password-backed native screen lock, Super+L, and optional idle locking. Screen locking does not encrypt your disk.
Find your comfortable view.
Text scaling, contrast choices, and keyboard controls help adapt the interface. Full assistive-technology compatibility is not verified.

Lunex OS 0.8
Live image & whole-disk installer
ISO release on hold
The 0.8 ISO is not yet available. Final installation acceptance and upstream source/distribution review are still in progress.

- Boot support
- BIOS & UEFI · Secure Boot unsupported
The new ISO is not available from this page yet.
The source archive covers Lunex integration code and build locks. It is not the complete source for every bundled upstream component. Source information
Lunex is a Linux-based system with its own interface. It is not Windows, macOS, or a native WinUI application. App and hardware compatibility vary.
A little preparation goes a long way
Try first.
Install thoughtfully.
- 01
Verify your download.
Compare the ISO’s SHA-256 with the published checksum before using it.
How to check the file - 02
Explore in a VM.
Boot the live image and try the desktop. Live files and settings disappear at shutdown.
- 03
Choose a spare disk.
Only install after backing up. Review the exact target disk and the erase confirmation.
Already using Aster 0.7?
A fresh install erases the selected disk. Use only the separate exact-version offline repair when it is available and confirms your installation is supported. It cannot recover a Wi-Fi password already forgotten by 0.7.
Deliberate by design
Updates you
choose to apply.
Lunex 0.8 includes a manual, signed desktop-update framework. You review an available release, download its verified files, and apply it from the installed system’s rescue console.

A few things to know
Clear expectations.
Better first steps.
Can I install any Linux package?
No. The importer supports only compatible, self-contained portable DEB, RPM, and Type-2 AppImage applications. It is not apt or a general Debian/Fedora compatibility layer. Unsupported architectures, installation scripts, system-level changes, and unresolved dependencies are rejected. Publisher signatures are not verified, and imported apps run as your user without a sandbox.
Will Lunex work on my PC?
The release is intended for x86_64 systems and has virtual-machine test coverage only. Graphics, sound, storage, Wi-Fi, firmware, and other physical-device compatibility can vary. Secure Boot is not supported. Try a VM first, then a live session on a spare device before considering an install.
Is this ready for my everyday or work computer?
It is an experimental release. The installed system is single-user, signs in automatically, and uses an unencrypted disk. The screen lock does not protect against reboot, physical rescue access, or malicious same-user X11 apps. Keep independent backups and avoid shared/public machines and sensitive data.
What gets saved between sessions?
Live-session files, installed apps, and settings are held in RAM and disappear at shutdown. On an installed system, home files and supported settings persist. Wi-Fi remembering is optional; its credentials are saved with root-only permissions on the unencrypted disk.
Does the updater update everything?
No. The channel covers only a fixed set of existing desktop and integration files. It does not update the kernel, drivers, Firefox runtime, bootloader, or all applications. The production channel is not activated, and opening Settings does not contact a server.
