Trying to install the same deb from a terminal results in the following libpng12-0 sudo dpkg -i wps-office_10._a21_b Ubuntu Software simply fails to install WPS Office, without displaying any error message, so I opened the WPS Office deb with gdebi-gtk, which doesn't allow the deb to install, displaying this message: " Error: Dependency is not satisfiable: libpng12-0": This issue is not new, since Ubuntu dropped libpng12 with version 16.10, but those whom are upgrading from Ubuntu 16.04 to 18.04 LTS , as well as Linux Mint 19.* users, might not be aware of this and how to fix it. Libpng12 is no longer available in the Ubuntu repository archives and as a result, some applications that were not built with the newer libpng ( libpng16) library fail to install. This applies to any Ubuntu or Linux Mint flavor: Kubuntu, Xubuntu, Ubuntu MATE, Ubuntu Budgie, Linux Mint Xfce, Linux Mint Cinnamon, etc., as well as Pop!_OS or elementary OS. In this article you'll find a very easy to apply fix that will allow installing and running applications that depend on libpng12-0 in Ubuntu 18.04 LTS (or Linux Mint 19.*, which is based on Ubuntu 18.04), Ubuntu 19.10, 20.04 / Linux Mint 20, and Ubuntu 20.10.
