No ros folder under /opt

Navio / Edge Getting started
1

In Navio2 ROS setup, I see
pi@navio: ~ $ echo “source /opt/ros/kinetic/setup.bash” >> ~/.bashrc
pi@navio: ~ $ sudo /opt/ros/kinetic/lib/mavros/install_geographiclib_datasets.sh

However I don’t see there is ros inside of /opt folder, I am new to Navio2, anybody give me hand for this? thanks a lot!

Look at it like this:

pi@navio:/opt $ ls -l

Check your Emlid Navio distribution.

I use latest one (20191128) with update

pi@navio:~ $ sudo apt-get update && sudo apt-get dist-upgrade

Some ROS files are in the update

Sudo emlidtool ardupilot show:

or just after login you can read:

pi@navio.local’s password:
