I was lucky to have an extra raspberry pi that I had not been updated yet and that I knew worked. So I found the /usr/lib/aarch64-linux-gnu/libindidriver.so.1.8.5 (.5 version) from there and copied it over to my defunct updated pi.
I'm not sure where you could find the .5 version - perhaps someone could help answer that??
But here is what I did: I copied (scp) the libindidriver.so.1.8.5 file to my defunct update raspberry pi and placed it in /usr/lib/aarch64-linux-gnu/ directory, then:
rm libindidriver.so.1 # this was a link to the .6 lib
ln -s libindidriver.so.1.8.5 libindidriver.so.1 # now links it to the .5 lib
And started this up and voila, qhy and zwo were now working.
But the real issue here, is can someone please fix this in the release code?? This is sort of a show stopper ... !!
