The roscd command takes you to the ROS_ROOT directory, which is not
your home directory. If you've used a system-wide installation, such
as from the debs, this will be in a restricted read-only part of your
filesystem where you do not have write-permission, hence the failure.
Your "home directory" (usually located at /home/username) in linux can
typically be reached using "cd" or "cd ~". It is the directory on the
computer where your user does have write permissions.
