Hi @Tamas-Pal-0 ,

Updates are through the apt package manager.  When new releases are available via SDK updates, you will be able to run `apt update && apt upgrade`.

Information on SDK releases are here, the latest release having `voxl-px4`
https://docs.modalai.com/voxl-suite/#v080

Information about our package management 'channels' are here, where you can choose to access earlier, pre-production releases if you want:

If you want to build from source and install, you can follow this guide, where you end up creating a `.deb` file and installing it the same that the apt package manager would:
