Robot model not showing in rviz

I am trying to work with this repository:

I did all the initial steps that are mentioned in the repo but have troubles showing the robot urdf in rviz. Since the people over there can't help I hope that someone here can point me in the right direction.

When I just want to load the urdf in rviz like this (in individual shells):

rosrun rviz rviz
roslaunch kuka_arm load_urdf.launch

I just see the gripper. You can see this in the first photo attached.

The urdf to me looks fine and there are no errors anywhere.

When I run the whole demo, like this:

rosrun kuka_arm

I can verify that the model is correctly loaded in gazebo as you can see in the second screenshot. I tried this on two computers, one in a VM, one natively and with integrated graphics and dedicated nvidia card.

Can anyone else please check the urdf and help me out in determining what the problem here is?

Do you have the robot description on the VM? Which computer is not showing the model?

I set up everything like it says in the readme on both. And it is not showing on either.

Some rviz users have encountered a similar issue on newer ubuntu/debian versions e.g. ROS Lunar on Ubuntu Artful or ROS Melodic on Ubuntu Bionic (see for example: ). The issue may be related to your locales.

If that's the underlying issue, modifying the following environment variable will fix it for you:

export LC_NUMERIC="en_US.UTF-8".

This was a lifesaver, thank you!
