Hi-
The ROS installation in /opt is protected, like other system files, to prevent undesired changes.
You can create all your ros packages in your home directory, for example:
cd ~/
mkdir ros
Before you can use ros tools in this directory, you need to add it to the front of your ros package path. The following line can be typed into the terminal, or added to the bottom of your ~/.bashrc file to automatically add the path each time you open a terminal:
export ROS_PACKAGE_PATH=~/ros:$ROS_PACKAGE_PATH
Then:
cd ~/ros
roscreate-pkg beginner_tutorials std_msgs rospy roscpp
Hope that helps,

roscreate works fine when I try it in my home directory.
Permission issues? What can the possible solution be?
Thanks.
