Hello, I had the same problem, a priori the documentation is no longer up to date.
Check out Github: github.com/jochym/pyindi-client/tree/master/pip/pyindi-client
If it's like for me I was missing the libindi-dev library.
Sorry about my average English
After reinstalling a Ubuntu Mate 18.04 version, everything is installed correctly. So this comes from the packages for 18.10, which have some problems.
I have problems when installing KStars on a Ubuntu Mate Cosmic distribution.
he can't find the package asi.common or gsc.
However, kstars-bleeding installs correctly, but of course drivers are missing.
What can I do that worked fine last week, but with an ubuntu 18.04?
Thank you in advance.
