No, with the held packages, libraspberrypi0 won’t be installed either, but install procedure will not complain about it either (it’s a firmware update you don’t want anyway, as it would break distribution).
Then the only dependencies problems reported are those described in post #p29708, which I resolved as explained in that post.
From there, plugin install does not fail and Pi boots normally.
Just the plugin does not fully work yet in my case due to X failing to start: maybe it’s a HDMI-specific issue as I do not use DSI port-based screen.
Maybe it’s fine for 7″ Touchscreen Monitor which this plugin is initially intended for?
So not completely resolved yet for me, but should be very close now…
Any idea for the X thing?
