To fix this issue, we’ll be using Pepper Flash Player, a safer and more stable version of Flash Player from Google. An Adobe Flash Player Pepper installer is available in Ubuntu 14.04 repositories. This installer downloads Google Chrome, extracts Pepper Flash Player and sets it up for Chromium usage.
To install Pepper Flash Player in Ubuntu 14.04, open a terminal and use the following commands:
sudo apt-get install pepperflashplugin-nonfree sudo update-pepperflashplugin-nonfree --install
Restarting Chromium will do. No need of a system reboot. I hope this quick post helped you to fix Adobe Flash Player issue with Chromium. Any questions or suggestions are always welcomed. Ciao
