    granwille,
    Thank you so much,
    but I get an error when I try to install libpng12-0:

    An error occurred while applying changes: dpkg: error processing archive /tmp/libpng12-0_1.2.50-2+deb8u3_amd64.deb (--install):
    unable to install new version of '/usr/lib/x86_64-linux-gnu/libpng12.so.0': No such file or directory
    Errors were encountered while processing:

    In the tutorial, they say this:
    To download the libpng12-0 library package from Debian Jessie package repository...

    It may be that you need to get the correct Debian version. If you are on 15.11 Deepin, that means you are on the stable version, and in that case, you would need to find Debian Stretch. Which is Debian 9. This tutorial explains it for Debian 8.
    See this: https://www.howtoinstall.co/en/debian/stretch/libpng12-0 but do this at your own risk.
