Rosrun tab autocompletion crashes terminal
I have been using ROS Kinetic on Ubuntu 16.04 for some time now. After doing some kernel upgrades I run into a problem when running the rosrun command. When I hit the tab after writing rosrun the terminal freezes and crashes after few seconds. This does not happen for roslaunch or other ros commands. If I type the whole rosrun command with the node that I want to run it works as expected. Has anyone encountered this problem? There was a question regarding this that proposed some fixes that unfortunately did not work for me (deleting the contents of /var/crash and doing a clean build).
Edit:
The output of env |grep -i ros |sort is:
CMAKE_PREFIX_PATH=/home/pavel/catkin_ws/devel:/opt/ros/kinetic

where the ROS_PACKAGE_PATH contains a lot of packages, but to make it short I just put pkg1, pkg2.... in the output above.
What is the output of
env |grep -i ros |sort?I edited the question with the output
Have you sourced your workspace ? The variable ROS_PACKAGE_PATH should be
/home/pavel/catkin_ws/src:/opt/ros/kinetic/shareTry
unset ROS_PACKAGE_PATH, and thensource devel/setup.bash. Is the output the same ? (only forROS_PACKAGE_PATH)When I do a clean build
ROS_PACKAGE_PATHgives only/opt/ros/kinetic/share. After I source the workspace I get the same package path that was shown in the question. When i unset theROS_PACKAGE_PATHand source the workspace the package path is the same and the crash still occursHave you modified your
.bashrc? Moreover have you runsudo apt-get update, thensudo apt-get upgradeand finallysudo apt-get autoremove?Did that but it did not help. I had this added in my .bashrc:
Can you just try to
unset ROS_PACKAGE_PATHand thenexport ROS_PACKAGE_PATH=/home/pavel/catkin_ws/src:/opt/ros/kinetic/share(don't source your workspace after that and try the autocompletion) just to make sure the problem isn't with this variable not correctly set.
