thursday's profile - activity

Hi there, can't figure this out.

After following this to the letter:

http://wiki.ros.org/fuerte/Installati...

I am now trying to follow this:

http://robohub.org/up-and-flying-with...

Running 'rosdep update' does not work. I keep getting a permission error regarding some temporary pickle files in .ros/rosdep/sources.cache . I have tried setting all files in that directory to have all permissions for others but this has not worked. I've tried purging, reinstalling, etc, doesn't work. I cannot find a process that fixes this.

Any help at all would be greatly appreciated. Below is a complete error readout:

thursday@daedalus:~$ rosdep update

For further reference here are what some file permissions look like in folders that may have something to do with this:
