After 31.12.2020 flashplayer is on eol. Do I have to uninstall flashplayer and freshplayer or update will remove the package.
You will probably have to uninstall it yourself.
You originally installed it yourself. I guess that, at some time, it will disappear from the repo you used (probably packman), and will show up as orphaned.
I’m keeping it for now, because there is still one site that uses it. When that stops working, I will uninstall.
That one site (that uses flash) stopped working this morning. So I guess I’m done with flash.
I may wait a few days, but then I’ll uninstall flash – probably just before my next planned reboot. That will be packages “flash-player” and “flash-player-ppapi” to uninstall.
