I have dedicated my free time this Canadian Thanksgiving long weekend to firing up my Beaglebone Blue with Ubuntu 20.04 Focal-Fossa so I can use it with ROS2 Foxy.
I have one major request for rootfs image: add the configuration for the focal-updates and focal-security pools to the /etc/apt/sources.d
configuration file. Both in the image and in the image-builder configuration. Now that I think of it I will work out how to send a change to gihub beagleboard/image-builder later.
When I did that apt update && apt dist-upgrade
reported a upgrade of 189 upgraded, 8 newly installed
packages. That is only 2.5 years of updates .
And (most-important to me ) ca-certificates-java configured properly which I wanted for a ROS2 foxy install.
