Hello,
I am trying to install ROS on ubuntu 18.04 using this tutorial (How to Install ROS on Ubuntu 18.04 - The Construct). After following the tutorial, I tried to run roscore but I run into the error:
RLException: Unable to contact my own server at [http://localhost:65431/].
This usually means that the network is not configured properly.
A common cause is that the machine cannot connect to itself. Please check
for errors by running:
ping localhost
For more tips, please see
http://wiki.ros.org/ROS/NetworkSetup
The traceback for the exception was written to the log file
I may have messed up some files when I was trying to install husarnet. The bottom of my .bashrc looks like this:
export PATH="/home/musicboy/anaconda3/bin:$PATH"
source /opt/ros/melodic/setup.bash
export ROS_HOSTNAME=localhost
export ROS_MASTER_URI=http://localhost:11311
export ROS_IPV6=on
And my /etc/hosts looks like this:
# This file was automatically generated by WSL. To stop automatic generation of this file, add the following $# [network]
# generateHosts = false
127.0.0.1 localhost
127.0.1.1 LAPTOP-E7I1REEH.localdomain LAPTOP-E7I1REEH
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
I am unsure how to proceed from here. I would like to install ROS on my computer so that I may run gazebo on it, but it seems that one of my settings is incorrect. I have tried uninstalling and reinstalling ROS, would anyone know what the problem is? Please let me know if you need any more information, I’d appreciate any help!
