I just installed with --install-suggests on Lubuntu 18.04. BAD idea. DON’T ever do that. It downloaded 5 GB and installed tons of stuff that seems to have little to do with Kicad, for example “Claws Mail”.
Had to look into the package installation logs and create a script to uninstall all that.
The worst part is that Kicad greeted me with a ton of “library not found” errors.
I will just uninstall everything, and reinstall without that “–install-suggests” switch.
