turtlesim's draw_square only draws 3/4 of the square (like "|_|") and then it spins forever

edit

The draw_square node from the turtlesim package, if installed from source https://github.com/ros/ros_tutorials , only draws "|_|" (3/4 of the square instead of a full square) and then the turtle spins forever.

Strangely, if I run draw_square from the built-in turtilesim everything looks normal. Has anyone encountered this issue?

Alternatively, I would need to know how to get the exact source code that was used to build into the built-in turtlesim.

I tried to retrieve source with "apt-get source turtlesim", but the command failed saying that "E: Unable to find a source package for turtlesim". Also I am unsure whether that command would retrieve the right version. Any idea? Thanks.
