Download Lirix

Version 1.0 Beta · released October 26, 2026

This is a Beta. Lirix 1.0 Beta works well in our tests, but it is new. Try it on a spare PC or in a virtual machine first, and back up your files before installing it next to Windows.

Lirix 1.0 Beta for 64-bit PCs

One file for everything: try Lirix, install the desktop, or install the server edition.

Download ISO (3.3 GB)

File	`Lirix-1.0-Beta-amd64.iso`
Size	3.3 GB (3536535552 bytes)
Based on	Debian 13 "trixie", KDE Plasma 6
For	64-bit Intel or AMD PCs (x86-64). Starts on both UEFI and older BIOS computers.

SHA256 checksum (download the .sha256 file):

eaae37d44c6ea14525ccfecd0b76237d777afbca8bad9caf4a65aa06ccfdeea0

Check your download

The checksum is a fingerprint of the file. If your copy gives the same fingerprint, it arrived complete and undamaged. This takes a minute and is worth doing.

On Windows

Open the folder where the ISO was saved (usually Downloads).
Click the address bar at the top of the window, type powershell and press Enter. A blue or black PowerShell window opens in that folder.
Copy and paste this line, then press Enter:
```
Get-FileHash .\Lirix-1.0-Beta-amd64.iso -Algorithm SHA256
```
It may take a minute. The long code next to Hash must match the checksum above. Capital and small letters don't matter.

Or let PowerShell compare them for you. It answers True if they match:

(Get-FileHash .\Lirix-1.0-Beta-amd64.iso).Hash -eq "eaae37d44c6ea14525ccfecd0b76237d777afbca8bad9caf4a65aa06ccfdeea0"

On Linux

Download the .sha256 file into the same folder as the ISO, open a terminal in that folder and run:

sha256sum -c Lirix-1.0-Beta-amd64.iso.sha256

It should say Lirix-1.0-Beta-amd64.iso: OK.

If the codes don't match, delete the file and download it again.
