Hey Folks!

I've followed this ROS - Tutorial:

https://www.youtube.com/watch?v=8ckSl...

http://moorerobots.com/blog/post/1

But when I want to Launch ROS I get this Errormessage:

enovm@enovm:~/mybot_ws$ roslaunch mybot_gazebo mybot_world.launch 

... logging to /home/enovm/.ros/log/9c283bdc-3614-11eb-a7b1-7d9aeb4bd4d2/roslaunch-enovm-30870.log
Checking log directory for disk usage. This may take a while.
Done checking log file disk usage. Usage is <1GB.

RLException: Invalid <param> tag: Cannot load command parameter [robot_description]: no such command [['/opt/ros/noetic/share/xacro/xacro.py', '/home/enovm/mybot_ws/src/mybot_description/urdf/mybot.xacro']]. 
Param xml is <param name="robot_description" command="$(find xacro)/xacro.py '$(find mybot_description)/urdf/mybot.xacro'"/>
The traceback for the exception was written to the log file

I've also checked if I have installed the newest version of xacro (using sudo apt-get install ros-noetic-xacro) My setup is:

Ubuntu 20.04 on a VM

ROS noetic

Python 3

Gazebo 11

I dont have much experience in ROS, so it is very confusing to me, that even the basic tutorial doesnt work. Thank you in advance!
