I have been trying apt install indi-full on an rPi running Ubuntu 21.10 and getting
[[The following packages have unmet dependencies:indi-full : Depends: indi-apogee but it is not installable Depends: indi-qsi but it is not installable Depends: indi-fishcamp but it is not installable Depends: indi-fli but it is not going to be installed Depends: indi-pentax but it is not installableE: Unable to correct problems, you have held broken packages.

I have Kstars running and I have enough indi installed to drive my mount and camera through Ekos, but I'm getting errors and whilst it seems unlikely, anything going wrong with the installation induces doubt. Its more likely related to libraw though.
