Daemon fails to start on Raspberry 4

[lummerland]

Hi,

since a while I try to get my lumicube to work, with no success. The installation works so far after doing it as supposed in https://github.com/abstractfoundry/lumicube/issues/19. But now the daemon does not start and I have no idea what to do.

I run systemctl --user status foundry-daemon.service with this result:

× foundry-daemon.service - Abstract Foundry Daemon
     Loaded: loaded (/home/lummerland/.local/share/systemd/user/foundry-daemon.service; enabled; preset: enabled)

I tried to find the reason for that in logfiles using journalctl -b | grep lumicube. Result:

Could this be the problem and how can I fix that? Thanks & regards!
