Choose the right artifact
Download the tarball that matches the Linux target. Cerbo GX and most 32-bit Venus OS installs use the ARMv7 artifact.
Download the current stable release, install it on the target device, then finish setup and activation from the local Phaeton web interface.
Run this as root on a Venus OS / Cerbo GX device. The installer downloads the latest ARMv7 release, verifies the signed SHA256SUMS manifest, installs to /data/phaeton, creates /data/phaeton/run.sh, and updates /data/rc.local for autostart.

Download the tarball that matches the Linux target. Cerbo GX and most 32-bit Venus OS installs use the ARMv7 artifact.
Download SHA256SUMS and SHA256SUMS.sig from the release page, use release-signing-public.pem from the public repository, verify the signature, then run sha256sum -c SHA256SUMS before installing.
Copy the tarball to /data, extract it into /data/phaeton, and keep all writable files under /data because Venus OS does not persist /usr/local or /etc.
Start /data/phaeton/phaeton, open http://<device-ip>:8088/, create the admin account in the first-run wizard, then complete activation.
