Error during first time setup

Hi Hello Robot team,

I’m setting up my second robot and running into an error that didn’t appear last time (in May).

I’m following these instructions: stretch_ros/install_noetic.md at dev/noetic · hello-robot/stretch_ros · GitHub

When comes the time to run stretch_robot_home.py after successfully running all previous commands, I get the following error:

Any idea what’s wrong?

Thanks team!

Hi @Theophile_Gervet,

The udev rules that manage how USB hardware appears on the system have likely not been configured correctly. This can happen if there was an error that causes the install scripts to error out before reaching the udev set up section. A log of the install is logged to ~/stretch_user/log/<datetime>/ directory as a zip file. Can you attach it here?

I can’t find a way to attach a zip file here. Sending this by email.
