build-essential is already the newest version (12.4ubuntu1).
You might want to run 'apt --fix-broken install' to correct these.

This seems strange: you have configured
aptto download package indices for Ubuntu Trusty (ie:14.04), but then askapttoinstall ros-melodic-catkin. ROS Melodic is only supported on Ubuntu Bionic (ie:18.04) so that cannot work.You cannot install ROS Indigo packages on 18.04 either.
You've tagged your question with
ubuntu-18.04.Can you please clarify which version of Ubuntu you are using and which version of ROS you want to install?
Sorry for the confusion. I have indigo... I also did this: notsotechnical@notsotechnical-VirtualBox:~/build/build$ sudo apt-get install ros-indigo-catkin [sudo] password for notsotechnical: Reading package lists... Done Building dependency tree

I have Ubuntu 18.04 on a virtual machine
you've cross-posted this question to SO within an hour of your post here on ROS Answers?
Which is it?
ROS Indigo only works on Ubuntu Trusty. ROS Melodic only works on Ubuntu Bionic.
You cannot have both.
Hey I have melodic
Can you please show us the output of
lsb_release -aanduname -a?please understand: 'melodic' is the name of a ROS release, not an Ubuntu release. Ubuntu is your OS (ie: a Linux distribution). ROS is "just" a set of programs that run on top of your OS. Compare with Windows: if I ask you which Windows version you have installed, you cannot answer with "I have Office 2016".
Now by circumstances, if you say "I have melodic", we can sort-of assume you are running Ubuntu Bionic as your OS. But we need to be sure. So please run the two commands I've asked you to run and show us what the output is.
Hi! The output outputs of lsb_release -a and uname -a are:
