Hi all. Trying to install drivers for the Astromechanics focuser and am running into many issues. I'm following the instructions from here indilib.org/devices/focusers/astromechan...lens-controller.html which look pretty simple but not so much in reality.

I need to add the repository but when I do it errors out. The command to add the repository is

sudo add-apt-repository ppa:mutlaqja/ppa
Which results in this.
Traceback (most recent call last):
  File "/usr/bin/add-apt-repository", line 95, in <module>
    sp = SoftwareProperties(options=options)
  File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 109, in __init__
    self.reload_sourceslist()
  File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 599, in reload_sourceslist
    self.distro.get_sources(self.sourceslist)
  File "/usr/lib/python3/dist-packages/aptsources/distro.py", line 93, in get_sources
    (self.id, self.codename))
aptsources.distro.NoDistroTemplateException: Error: could not find a distribution template for Raspbian/buster

Can anyone please help me?
