Hi all,

I am new to the ROS community, apologies if this question seems trivial to some of you.

I was trying to install smach_ros package since I wanted to play around with hierarchical based state machine implementation. But I am having trouble installing it on my system.

I tried running this on my terminal:

sudo apt-get install ros-foxy-smach-ros

But I get this:

E: Unable to locate package ros-foxy-smach-ros

Is the smach library not ready to be used with foxy? Is there any work-around for it?

Thanks.
