Super new at linux, and I want to program robots.
I'm trying to work with ROS 2 in Ubuntu 22.04. I installed Ubuntu into a virtualbox with the iso. The very first thing I did without any changes was to open a terminal and start filling in commands from https://docs.ros.org/en/humble/Installation.html
Every time I put in a command I get this output:
/etc/sudoers:1:5: syntax error
exit
^
Then sometimes the command runs but not this one:
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg
Can anyone tell me what I'm doing wrong.
Thanks
