sudo apt install catkin not working.
Hi, I'm a newbie, so sorry if this is really obvious. I'm following the Tutorials instructions having just installed ROS on Ubuntu Mate. The current step says
$ cd ~/catkin_ws/ $ catkin_make
but when I enter "catkin_make" terminal returns
The program 'catkin_make' is currently not installed. You can install it by typing: sudo apt install catkin
So I do that, and get
Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help resolve the situation: The following packages have unmet dependencies: catkin : Depends: python-catkin-pkg but it is not going to be installed E: Unable to correct problems, you have held broken packages.
It then ends at that. How can I fix this and continue with the tutorials?
what ROS distro are you using????
