Update: I removed QtPy4 Full Install (PR1.2) - not sure why that was installed! Also managed to install extmouand Patched x.org Mouse Driver, trying to find the right combination of packages/dependenciesthat will allow BT-HID-Scripts to be installed.

Alas, I still get the last four lines quoted above as the log output error when attempting the install. Is there something wrong with the package?
