In order to install the client on Debian 9 (stretch) I’ve had to get libpng12-0 installed from Jessie here:
https://packages.debian.org/en/jessie/amd64/libpng12-0/download
Then had to create symbolic link for libffi.so.5
to the newer version that’s installed.
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libffi.so.5 /usr/lib/x86_64-linux-gnu/libffi.so.6
