ROS Packages Not Found in Ubuntu 20.04

I wanted to give ROS a try on my Ubuntu 20.04 machine and I installed the ROS packages as per instructions given in the ROS website, but after successful installation, roscd fails with command not found:

joesan@joesan-InfinityBook-S-14-v5:/opt/ros/noetic$ roscd
bash: roscd: command not found
joesan@joesan-InfinityBook-S-14-v5:/opt/ros/noetic$

Here is the content inside the noetic folder:

joesan@joesan-InfinityBook-S-14-v5:~$ cd /opt/ros/noetic/

As you can see I have this line in my .bashrc as well:

# Source the ROS setup profile
source /opt/ros/noetic/setup.bash

Any ideas why I could not get roscd command working? I installed the full version:

sudo apt install ros-noetic-desktop-full

Is there anything that I'm missing?

Solution

  • So finally I was able to get this resolved! I have a .bash_profile where I have all my user specific commands and shortcuts. In this file I also source additional setup files. So what I did now was to remove the source command for ROS from the .bashrc and put this in the .bash_profile file and source the whole .bash_profile file from within .bashrc like this:

    if [ -f ~/.bash_profile ]; then
    . ~/.bash_profile
fi

    In the .bash_profile, I have the source command like this:

    # Source the ROS setup profile
source /opt/ros/noetic/setup.bash

    This help me fix the error!
