Even MX-14 & Mepis 12 have a problem with the newer flash if what we found in this post from last year still applies: http://forum.mxlinux.org/viewtopic.php? ... e1#p391612uncle mark wrote:...That said, I now seem to have a flash problem. It no longer appears in about:addons. I've downloaded the tarball from Adobe (dated 2017-07-24) and dropped libflashplayer.so everywhere I can think of. Still running into a lot of videos -- mainly in forums and Twitter links -- that won't play.
Flash version 23 needed a newer libc6 version than the 2.13 version available in Wheezy, Mepis 11 was based on Squeeze and used an even earlier libc6 version (I forget the version now though).
