I'm on 32 bit Lubuntu 16.04 and Chromium has the usual Flash version 11.2.9. A bunch of things won't play correctly so I've been trying to find a way to install Pepper Flash for a while and I'm not sure how to proceed.
I have the canonical repo enabled and I've tried installing PPAs in multiple ways--the package is always missing or there's no release file. Almost every online thread about this is from 2014 and I'm very new to Linux and very confused. And now the terminal is also on a loop when I use sudo apt-get update--it keeps trying to update & install ppa:skunk/pepper-flash which has no release file.
I have the latest tarball from Adobe. Could I extract it and manually install the Pepper Flash plugin as root? If so how would I do this? (I found a guide for this for Firefox but it didn't work out because it was majorly outdated.)
Forgive me if I'm missing something obvious, I have a headache. Thanks a bunch for any input.
EDIT: This got flagged as a duplicate but it's not--I was asking how to/if I could install via a tarball as root while the other question did not specify that this method was exactly what they needed info about. It is similar but not a duplicate.
