Hello, as the description suggests this package uses GTK2 and python-gtk which is python2-only. It is not insurmountable to port an application to the new python and GTK, and I already ported something. However, I do not care about Xbox, and don't have one to test this. Upstream is dead unless there is a newer fork I missed. I will delete this package in a few weeks if nobody cares to update it. Thanks Michal
