If you prefer, we can say 'Won't Fix'. That's not completely accurate but has the same effect. A bug being 'Invalid' does not mean it's not a bug. It certainly is a bug, but it is a bug that's not from Ubuntu. So that makes the Ubuntu bug status 'Invalid'.
This bug is 'Invalid' because the problem is not coming from any Ubuntu code. The problem is in the code you downloaded from Github:
https:/ /github. com/loimu/ rtbth-dkms
which is also available in:
https:/ /launchpad. net/~blaze/ +archive/ ubuntu/ rtbth-dkms
but doesn't seem to be supported either way :(
