Hi everyone, I'm writing to you for some explanation about differences between Electric and Fuerte. I lately moved to the latter and spent some time to update several stuff I coded while on Electric. Today I was testing some package I wrote for the erratic robot (real, not simulated).

On Electric, I mapped the port_name param using a symbolic link in /etc/ folder, without having to change or giving any permission to any user. Needless to say, it always worked.

On Fuerte, I did the same things but as result of executing the erratic_base.launch contained in the erratic_player stack, I had

Erratic::Setup()::Open() permission denied

To solve the problem I changed the owner of the symbolic link mentioned before and everything went fine.

Long story short, is there any relevant between Electric and Fuerte regarding permissions, or something similar, I'm not aware of? Or something I did miss while reading about how to migrate?

Thanks you all, folks

Did you change Ubuntu versions at the same time?

I don't think any changes in the erratic_robot stack could cause this problem with permissions. I only updated parts related to Gazebo simulation to get erratic_robot stack working in Fuerte.

@joq: yes, from ubuntu 11.10 with electric to 12.04 with fuerte. I'm trying to understand if this issue could be related only to the OS
