Error Running ROS Setup

pi-top [4] Robotics Kit
#1

Fresh install and update of the PI-TOP O/S. Any thoughts regarding this error?

@pi-top:~ $ sudo docker run -it -v /dev:/dev --device-cgroup-rule=‘c 89:* rmw’ --device-cgroup-rule=‘c 81:* rmw’ -p 8022:22 -p 80:80 -p 8080:8080 -p 9090:9090 --name pt-ros-dev pitop/robotics-engine-ros:latest

sudo docker run -it -v /dev:/dev --device-cgroup-rule=‘c 89:* rmw’ --device-cgroup-rule=‘c 81:* rmw’ -p 8022:22 -p 81:80 -p 8080:8080 -p 9090:9090 --name pt-ros-dev pitop/robotics-engine-ros:latest

Try this instead, it’s because pi-topOS now already has a web server running on port 80, I’ve just changed it to be port 81 on the host OS. This means you’ll have to specifically go to this port if trying to use the web controller for ROS, i.e. http://192.168.X.XXX:81

Thx I’ll give this a shot today! Appreciate your support as always.
