Difficulty installing a dependency required to compile Doom 64 EX

I am on Ubuntu 14.04 on Crouton. My goal here is to compile and install Doom 64 EX. I am trying to follow the github guide seen here:

Under the bold section for prepare dependencies under Ubuntu I am stuck on the final command. Whenever I enter

$ sudo apt install git cmake libsdl2-dev libsdl2_net-dev zlib1g-dev libpng-dev 

into the command terminal it gives me this.

Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'libpng12-dev' instead of 'libpng-dev'
E: Unable to locate package libsdl2_net-dev`

I am unsure where to go from here.

Perhaps unrelated but one reddit user noted that one of the command terminal lines given earlier in the guide had a typo in it. In the guide it reads

$ sudo add-apt repository ppa:ubuntu-toolchain-r/test

When it should read

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test

Again perhaps unrelated but more typos may persist on the github page. Thank you.

Manual Installation

If you wish to install libsdl2-net-2 manually in Ubuntu, download the deb file from here.

This is a small, low-level, cross-platform networking library, that can be used with the Simple DirectMedia Layer library.

This package contains the shared library.
