I have a current Raspbian (Linux raspberrypi 5.10.52-v7+ #1441 SMP Tue Aug 3 18:10:09 BST 2021 armv7l GNU/Linux) running on a 3B+.
I installed Arduino 2:1.0.5+dfsg2-4.1. I can run this but, when it comes up it is a very limited installation. No library management option was the first thing I noticed.
Doing a verify/compile java spews out a lot messages (which I don't see on other platforms).
$ java -version
openjdk version "11.0.12" 2021-07-20
OpenJDK Runtime Environment (build 11.0.12+7-post-Raspbian-2deb10u1)
OpenJDK Server VM (build 11.0.12+7-post-Raspbian-2deb10u1, mixed mode)
I can't install the ESP32 tools, no board manager under Tools>Board>Board Managers
Is this the current state of 2.xxx ?? I'm suspecting that I need some other package but, have no idea what that might be.
Where have I gone wrong?
