When Ubuntu 18.04 LTS released, I have started testing different applications settings… the steps below is how I got Adobe Flash Player installed…
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.
If you’re going to be using the Google Chrome on Ubuntu desktop, then there’s no need to install Adobe Flash plugin. Chrome comes with its own bundled NPAPI version of Flash plugin installed. Flash movies and videos should just work with Chrome web browser.
Although the NPAPI version of flash comes with Chrome, the PPAPI version isn’t installed. To install the PPAPI version supported by other browsers, follow the steps below:
Step 1: Enable Canonical Partners Repository
The latest flash plugin lives in the Canonical Partners’ repository and is disabled by default. You must enable this repository before attempting to install flash plugin.
To do that, open the command line terminal and run the commands below.
After installing, restart Firefox or Chromium, or any other web browser before using the flash plugin. To make some changes to the plugin, click the Activities from the top left corner, then on the Activities Overview, search for Flash Plugin
Select it and to open. From there you can configure its local storage settings, control your privacy and delete temporary files and data.
