How to install Flash player on Ubuntu?

flashplugin-installer

sudo apt-get install flashplugin-installer

The flashplugin-installer package provides the NPAPI plug-in for Firefox. If you chose to install certain third-party software when you installed Ubuntu, flashplugin-installer is probably installed already. Otherwise you can install it and restart your browser.

Install the Flash plug-in

Flash is a plug-in for your web browser that allows you to watch videos and use interactive web pages on some websites. While HTML5, which is a more modern solution, is increasingly offered, there are still some websites which won't work without Flash.

If you do not have Flash installed, you will probably see a message telling you so when you visit a website that needs it. Flash is available as a free (but not open-source) download for most web browsers.

There are two kinds of plug-ins available:

• NPAPI for Firefox and other Gecko-based web browsers
• PPAPI for Chromium and other Blink-based web browsers including Opera and Vivaldi

  Some features of the PPAPI plug-in, such as 3D acceleration and premium video DRM, are not available in the NPAPI plugin. If you use Firefox or some other Gecko-based browser and need those features, you can install the browser-plugin-freshplayer-pepperflash package. It's a wrapper which makes Firefox use the PPAPI plug-in.

  1. Make sure that adobe-flashplugin is installed.
  2. Open a terminal window by pressing Ctrl+Alt+T and install the browser-plugin-freshplayer-pepperflash package:
     sudo apt install browser-plugin-freshplayer-pepperflash
  3. Restart your browser.
