ISAAC ROS GEMS configuration

Hello,

For using ISAAC ROS GEMS packages listed at NVIDIA Isaac ROS · GitHub, there is confusion in terms of minimum requirements for x86 system to build the image.
As per GitHub - NVIDIA-ISAAC-ROS/isaac_ros_visual_odometry: Visual odometry package based on hardware-accelerated NVIDIA Elbrus library with world class quality and performance. , Ubuntu 18.04+ is recommended, however it has dependency on isaac_ros_common at path GitHub - NVIDIA-ISAAC-ROS/isaac_ros_common: Common utilities, packages, scripts, Dockerfiles, and testing infrastructure for Isaac ROS packages., which says Ubuntu20.04+ is recommended for x86

Please let me know what is the minimum x86 OS (Ubuntu18.04 or Ubuntu20.04) required for using ISAAC ROS GEMS packages ?

Thanks
Gurpreet

Isaac ROS GEMs have only been tested on Ubuntu 20.04 on x86. The docker container from Isaac ROS Common to run these GEMs uses Ubuntu 20.04 and can be built/launched on host machine running 18.04+. We’ll get rid of the confusion and just update any remaining references to Ubuntu 20.04+.
