Hey guys, I installed ROS jade instead of ROS indigo and I keep getting the following error while installing the rosdep. Someone knows what to do?

edit

martin94@ubuntu:~$ sudo rosdep init
ERROR: default sources list file already exists:
    /etc/ros/rosdep/sources.list.d/20-default.list
Please delete if you wish to re-initialize

This you can ignore (unless you want to re-initialize): you only need to run sudo rosdep init once, even if you (re)install a different version of ROS.

martin94@ubuntu:~$ echo "source /opt/ros/indigo/setup.bash" >> ~/.bashrc
martin94@ubuntu:~$ echo "source /opt/ros/indigo/setup.bash" >> ~/.bashrc

If this is an actualy copy/paste, then again: you only need to do this once. The >> will cause bash to append the line you give to echo to the .bashrc file, so you'll now have multiple. That is not really an issue, just unnecessary.

martin94@ubuntu:~$ source ~/.bashrc
bash: /opt/ros/jade/setup.bash: No such file or directory

Are you sure you have installed ROS Jade on this machine? This basically tells you that bash was unable to find setup.bash in the /opt/ros/jade directory. A successful installation of ROS Jade should have placed that file there.

Can you add the output of ls -al /opt/ros to your original question? Please use the edit button / link for that.

Also: please add on which OS you are doing this (ubuntu, yes, but which version?).

Edit: seems you edited your question title (old title: "Hey guys, I installed ROS jade instead of ROS indigo and I keep getting the following error while installing the rosdep. Someone knows what to do?"). My previous answer assumed you had Jade installed, not Indigo.

output of ls -al /opt/ros:

martin94@ubuntu:~$ ls -al /opt/ros
[..]
drwxr-xr-x 7 root root 4096 Aug 26 20:06 indigo

From this (and from your updated question title), it seems you only have Indigo installed, but your .bashrc is still trying to read the setup.bash file under /opt/ros/jade. You don't have that, hence the error (the No such file or directory error, not the rosdep error, that is unrelated).

Open .bashrc, and look for a line source /opt/ros/jade/.. at the end of it. Remove any lines that have source and jade in them.
