System Raspberry Pi 2 B Raspbian GNU/Linux 9 (stretch) What I tried Download install file: `wget https://github.com/hyperion-project...ha.9/Hyperion-2.0.0-alpha.9-Linux-armv7l.deb` For install I've tried both in different installation attempts: `sudo dpkg -i Hyperion-2.0.0-alpha.9-Linux-armv7l.deb` AND after uninstalling `sudo apt install ./Hyperion-2.0.0-Linux-x86_64.deb` Then because I found a few mentions of this: `sudo systemctl disable --now [email protected]` `sudo systemctl enable --now [email protected]` `sudo reboot now` After reboot I see: `Dec 03 07:46:52 raspberrypi systemd: Started Hyperion ambient light systemd service for user root.` but when I navigate to the rpi's IP on port 8090 or 8091 nothing loads. I've also tried: `sudo /usr/bin/hyperiond -d` The logs hang at ` <DEBUG> Hyperion.cpp:562:handlePriorityChangedLedDevice() | No source left -> switch LED-Device off` and do not proceed. What else can I try? Did I miss a step in the install? I'm just following this: https://docs.hyperion-project.org/en/user/Installation.html#supported-browsers I would prefer to not use the HyperBian image.
