I’m seeing that, plus several other version conflicts. It looks like the `.deb` installer only works in actual Debian, not Debian based distros. I also tried the AppImage. It runs, but for me it gets i2c/SMBus error when it tries to detect devices. I found a forum thread on it and they said the only way to fix it is to patch your kernel (not something I want to get into) or wait until an update to either your distro or OpenRGB fixes it. Some people say it was running fine in Ubuntu until an Ubuntu update early this year. It’s a nice project, but it has to deal with specific, non standard hardware control so it’s prone to issues like this. At least they seem to know what is going on. This may get fixed.
