E: Unable to locate package libgtk2.0-dev

Question

I get the following error:

E: Unable to locate package libgtk2.0-dev
E: Couldn't find any package by glob 'libgtk2.0-dev'
E: Couldn't find any package by regex 'libgtk2.0-dev'

In trying to install:

apt-get install libgtk2.0-dev 

I have:

Linux 0803156b7532 4.15.0-15-generic #16~16.04.1-Ubuntu SMP Thu Apr 5 12:19:23 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Also, I get (as a root):
