Hello Cliff (enkiduonthenet)

We know that these flash players are about to disappear forever, but
while that does not happen officially should not work normally? This
problem is recurrent in the majority of Linux distros, where after
upgrades, either distro or browsers something happens in adobe flash
player plugins or in the famous Opera ffmpeg. For ffmpeg I found a
definitive solution for some distros that insist on not working, but for
the flash player not yet.

Note: In an attempt to find out why Opera Browser, using the adobe flash
player plugin does not work, I ended up finding the command to run Opera
via sandbox and thus, using it through the terminal, the adobe flash
returns to normal operation.

NOT SANDBOXED


For Google Chrome also only works the adobe flash player plugins in sandbox

What may have caused such discomfort?
In some distros Linux as in the case of MX Linux is working normally, in others also only work in sandbox as is the case in Ubuntu 19.04.

As in Manjaro it is easy to review the adobe flash player's
dependencies, I saw that there is a file called glibc 2.29 that was
updated in this package yesterday, and it is precisely in distros that
their browsers do not work. Already for the distros that work the adobe
plugins are with this file glibc previous to 2.29. I do not know if this
is the real problem, but I think it should be investigated for this
inconvenience that adobe plugins only work in sandbox in some cases.

The problem seems to be really related to glibc version 2.29.
So the next version of chromium should solve this problem that has been dragging on for years.
