No 'ros' stack detected in candidates, ¿where is the stack?

edit

Hi.

Sorry for disturbing you, i'm trying to install ROSGroovy in Slackware 14.0.

How can this be solved?

(Over-)Writing /home/user/ros/.rosinstall (Over-)Writing setup.sh, setup.bash, and setup.zsh in /home/user/ros ERROR in rosinstall: No 'ros' stack detected in candidates []. Please add the location of a ros distribution to this command.

I have googled this error, and found that rosinstall is pointing to an empty url.

I also found that the ROS files coulbe in the /ros directory, but there are no files in the ros directory

My problem is, how can i fix that rosinstall is pointing to an empty url? Or where are the files to install ROS?

I would greatly appreciate your help.

Thanks in advance.
