I created a fresh Ubuntu V20.04 sim and placed it in a 4G RPI4 then:
apt-add-repository ppa:mutlaqja/ppa
apt update
apt -y install indi-full kstars-bleeding
Noticed that in /usr/lib/aarch64-linux-gnu/, libindidriver .so.1 is linked to the .5 version:
lrwxrwxrwx 1 root root 22 Apr 25 20:03 libindidriver.so.1 -> libindidriver.so.1.8.5
-rw-r--r-- 1 root root 1189152 Apr 25 20:03 libindidriver.so.1.8.5

kstars --version says 3.4.2

Which works.

Is this right - was the fix to go back to .5 version?
