Comment 8 for bug 1720908

Hi muzi
on my 32 bit still no success

on my 64 bit notebook, Flash kept working normal while FF upgraded to
version 56

on the Ubuntu17.10 beta artful with FF55, I had also problems getting Flash
installed.
But I found a nice site that lists all available Ubuntu packages, called
https://packages.ubuntu.com
selected the artful packages and found flash installer.
downloaded that package via the local ubuntu distribution site, that
offered me a deb package which installed without a problem and made Flash
working corrrectly.
