Flash Player will reach EOL in 5 months, see https://www.adobe.com/products/flashplayer/end-of-life.html. I think it should already be removed from cauldron as there won't be any security release from Adobe when Mageia 8 is released.
Marc attempted to remove it, but I think task-obsolete may not work with the buildsystem anymore for non-core packages. I think Jani made a task-obsolete-nonfree to work around that. Also freshplayerplugin and anything else dependent on or associated with Flash should probably be removed.
Thank you Frédéric for raising this.
Assigning to all packagers, Jani already CC'd.
In fact, I did not find flash-player-plugin in Cauldron. Perhaps it has already been removed, in which case this bug can be closed.
