I have Odroid-C4 too. OS: official image of Ubuntu 20.04 + Mate. I tried to install Indi and KStars, but I was unsuccessful. The installation ended with a codename error - expected "Bionic" but is "Focus". The solution with --allow-releaseinfo-change was unsuccessful. Can You, please get, a more detailed description how you installed the Indi to C4?
I'm new to Linux. Thanks
