Using Ubuntu 14.04 with ROS Indigo installed. Trying to implement Moveit example for baxter.

I updated the baxter to the new sdk. Version 1.2.

Runnig

roslaunch baxter_moveit_config baxter_grippers.launch

gives me this error

It sounds like your Debain ROS installation is in a broken state. I believe roslaunch is telling you that xacro failed to create the SDF file. This is likely due to using an old version of xacro. I recommend updating your install:

$ sudo apt-get install --only-upgrade ros-indigo-xacro

If that doesn't work, you may need to update your entire set of ROS packages. The best way I know of for this (please correct me if I am wrong here):

$ sudo apt-get dist-upgrade

That will upgrade all of your out of date packages (ROS and otherwise), and remove any old and conflicting packages.

Still no luck. The roslaunch command still gets stuck.

I updated the xacro. Now the roslaunch command does not execute fully.

On terminating I get an error of this sort . .
