Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package ros-melodic-gmappin

gmapping has not been released into Melodic, so that's why you can't install it using apt-get.

See #q303253, #q296170 and wiki/slam_gmapping. Notice how the wiki page has no version button for melodic. The status page for Melodic also doesn't show any gmapping packages (meaning it hasn't been released).

As far as I understand there are also no plans to release it for Melodic. I can't find a reference, but I believe the idea is that other packages (such as Google's Cartographer) are much more powerful and feature complete, or at least much better maintained.

If you really want/need gmapping on Melodic, you could attempt a from-source build.

You may refer to #q300480 for a workflow that resulted in a successful build at the time the answer was written.
