Ubuntu – Flash with Chromium or Google Chrome broken on Ubuntu 19.04


I tried loading Adobe Flash player in Chromium on Ubuntu 19.04 (Lubuntu in this case) using various answers on AskUbuntu.com. I get to the point where the Allow Flash popup happens. But when I click to allow it, it says "Right-click to run Adobe Flash Player". When I rightclick and choose Run this Plugin, nothing happens. I've tried to apply fixes using the Pepperflash technique, as well as the Adobe Flashplugin technique.

Update 2019-05-29:
This is now fixed for Chromium via chromium-browser 74.0.3729.169-0ubuntu0.19.04.1.
(Not yet for Google Chrome, though.)

Yep, it's a known bug. Someone posted the Chromium fix for Ubuntu 19.04 finally.

First, let's get a clean slate:

sudo apt-get --purge remove chromium-browser
sudo apt-get --purge remove adobe-flashplugin

Do the following to find a list of all the pepper stuff and then get rid of it with apt-get --purge remove ___package-name___

sudo apt-cache search pepper | grep -i pepper | grep -i flash

Now, visit here with Firefox (since you don't have Chromium):


Look for Builds. Find one that fits your architecture. Mine for instance was AMD64. I clicked that. Now, from this list, you need to download two binary packages:

chromium-codecs-ffmpeg 74.0.3729.131-0ubuntu1
chromium-browser 74.0.3729.131-0ubuntu1

(Note when you click those links above on that web page, it will take you to a page that says "Downloadable files" and will have your deb file to download.)

Once both deb files are downloaded, use the dpkg command to install, starting with the ffmpeg file first:

sudo dpkg -i chromium-codecs-ffmpeg*
sudo dpkg -i chromium-browser*

Now go into your GUI-based Apt Package Manager and look for Software Sources. Click the Other Software tab. You'll see 2 items called Canonical Partners -- click the one that is not the Source Code version and click OK or Close to enable it.

Next, at command line, do:

sudo apt-get update
sudo apt-get install adobe-flashplugin

Now launch Chromium. When viewing a Flash component your first time on a given domain, Chromium will act kind of dumb and tell you that you need to install Flash. Click the link to install Flash. It won't actually install Flash. Instead, a security prompt will appear to ask if you want to enable Flash. Do so. The page will load your Flash component. You can go to this page to test if you have Flash installed. Note if you see a puzzle piece, click it, choose Enable Flash, and you should see flash content like an ad plus a "Version Information" box appear. That means you have flash enabled.

Here's something else to note. Adobe's newer flash test page is broken when viewed from Linux Chromium. It provides the wrong answer. Instead, use the older flash test page, click the puzzle piece, enable Flash, and you'll see Flash content appear if you have done these steps properly.
