# Revision history [back]

So here's what I've done:

I followed the installation steps again: http://wiki.ros.org/Installation/Ubuntu

Afterwards, I was able to install husky via apt-get:

$sudo apt-get install ros-melodic-husky-simulator Then, there was no problem. By the way, instead of sourcing my workspace, I directly used command line to launch Husky, in other words, I wrote$ roslaunch husky_gazebo husky_empty_world.launch to the command line. I later removed my workspace, it was messed up.
