I have recently attempted to install mupen64plus on my Lubuntu machine. After doing this command:
sudo apt-get install mupen64plus
the install proceeds without error and everything sets up ok. But after I run the program, I get an error message about libpng16.so.16 not being present on the system. After doing a complete search of the file system, I could not find the shared library anywhere. So, is there a package or source repo where I can install this MIA shared library file into /usr/share/lib? After doing several Google searches of my own, I could not find anything to the effect. As far as I can tell, nobody has had this issue, or so few have had it that Google can't find anything about it.
