install desktop-full is not working

if I try sudo apt-get install ros-kinetic-desktop-full

it says:

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 to resolve the situation:

The following packages have unmet dependencies:
 ros-kinetic-desktop-full : Depends: ros-kinetic-simulators but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I tried everything to solve the broken packages problem but nothing worked.

Have you at any point installed Gazebo stand-alone on this machine? A common cause for these types of errors is a dependency of ros-kinetic-simulators is already installed and is a newer version than what the ROS packages need/want. Ubuntu cannot uninstall that newer dependency and as a result it cannot install ros-kinetic-simulators for you.

I can only suspect you have installed some ros packages from a more up to date version of ros, I believe this is more likely due to the dependency on ros-kinetic-simulators which was introduced in Melodic. I can only suggest you remove all presence of ros, purge and removal is pretty well documented on here, then try the reinstall following the wiki. If working on a fresh workstation I'd just suggest just reinstalling linux afresh at this point to minimise risk after backing up your files as some of these functions can be used improperly or finding later that an undesired package is causing problems.

Hopefully this helps!
