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.
