[Pkg-electronics-devel] Bug#1089063: kicad: pcbnew does not launch, error missing symbol

[Brian]

I had time to spin up the VM and try it today...and the problem did not 
reproduce.  pcbnew ran as expected.

I don't know what happened the first time, but if I can't reproduce the 
problem, there's nothing for the package maintainers to fix. Maybe 
something about my system got bungled up as I fought with getting nVidia 
drivers installed.  Who knows?

Anyway, thanks for your attention!
Cheers,
-Brian
