Downloads

Releases.

GitHub Releases are the update channel: each release ships the dd-able USB image for humans plus the sysupdate transfer set and SHA256SUMS for machines. Installed systems pull these automatically; below is the same feed, live from the GitHub API.

Latest

Flash the USB image, boot from the stick, and install to disk when ready (see Getting started):

# 1. Download lisa-usb-<version>.raw.zst below, then:
zstd -d lisa-usb-*.raw.zst -o lisa.raw
sudo dd if=lisa.raw of=/dev/<your-usb> bs=4M status=progress oflag=sync

# 2. Boot it. To install onto the internal disk (erases it):
lisa install /dev/<internal-disk>

# 3. Update in place later (A/B, auto-rollback on a bad boot):
lisa update --reboot

Could not reach the GitHub API just now — see the releases page on GitHub.

The [lisa] package repo

Already on Arch (or Omarchy)? Lisa's components are ordinary pacman packages in a signed repo — the same packages the OS image is assembled from. Add it and install what you want:

# /etc/pacman.conf — signatures are published; SigLevel goes
# Required once the keyring package has shipped in the image.
[lisa]
SigLevel = Optional TrustAll
Server = https://github.com/Lisa-AgenticOS/lisa-packages/releases/download/current

# then
sudo pacman -Sy lisa-cli lisa-apps lisa-desktop
