when I run sudo apt-get install ros-melodic-gazebo-ros-control it gives me

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package ros-melodic-gazebo-ros-control is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'ros-melodic-gazebo-ros-control' has no installation candidate

how do I solve this?

I have ros melodic and gazebo 9.14.0

sudo apt-get update
sudo apt-get install ros-melodic-gazebo9-ros-control

The reason it could be failing could be due to the way you installed ROS2, your particular OS, the way you installed gazebo, etc because those things effect weather a package can be installed or not. Please read http://wiki.ros.org/Support for guidelines on how to submit a clearer question so we can help!

@rydb I don't have ROS2, I'm on ROS1 melodic and I installed ros desktop full version on Ubuntu 18.04. other dependencies are installed without any problem like joint position control, joint effort control etc
