So we used to be able to use a pre-made package for Debian to install the Flash plug-in in Chromium ( namely: pepperflashplugin-nonfree ). It seems that package is now broken. (Because the package in the past extracted the plugin from the Chrome package, but that package no longer contains Flash, and Chrome instead downloads it later IIUC .) I am able to download the appropriate ppapi plugin, from Adobe directly, but I can't seem to be able to make Chromium detect it. There is a text file with instructions included that says to copy it into some directory, but it seems distribution specific, as I found differing instructions for Gentoo.
There's a lot of info on this out there, but most is outdated, or about how you should just use npapi on Ubuntu. I have no problem with using the npapi version on Chromium, if that's an option. Hopefully somebody has some solution out there. I am thinking about looking through the source code for pepperflashplugin-nonfree and the version 52 of Chrome packages to see how it used to be configured... but I'm not adept at that.

Hi...

Where did you extract to or place the "libpepflashplayer.so" and the "manifest.json" file? In my system, they're located in "/usr/lib/chromium-browser/plugins." Try placing them there if they're not already.

Also, you might need to add a command to Chromium's startup. Open a terminal and open this file (using root privileges) with a text editor of your choice...

Then add this command to CHROMIUM_FLAGS...

It should look exactly as you see above. Be sure to change the flash player version number "11.5.31.2" to the one specifically stated in your "manifest.json" file that came with the package (Flash Player) from Adobe. Then save the changes and exit. Hopefully that will take care of the issue.

I had the same problem you're having now a while back (on my copy of Lubuntu 14.04) and the instructions above fixed it for me, which I originally found here by Craig Gomez. However, I can't guarantee they will work for you.

Let us know how it goes...

Regards...

You don't say what version of Debian you're using, but there is a fairly easy set of instructions on the Debian website that walks through installation for both 32 and 64 bit, supporting only Chrome/Chromium. This covers Debian 7 and 8, not sure if you've seen it:
https://wiki.debian.org/PepperFlashPlayer/Installing

Give that a shot first.
Debian isn't Lubuntu, and isn't that old version of Lubuntu either...the instructions you reference are FIVE YEARS OLD, and at best, reference the Adobe Flash plugin, which isn't officially supported any longer, and isn't the pepperflash plugin the OP asked about.

Yes, it is the Pepperflash version, as can clearly be seen from my instructions. Really, I'm getting tired of you doing this and I ask that you cease.

Reported.

The PPAPI flash is available at adobe.com now. It was stripped from chrome version 54? +

I just use the freshplayerplugin in firefox plus the ppapi flash version. Although I only install it in $HOME/ for one user. Everything else works well enough under html 5.

Report whatever you'd like, and I'm getting tired of having to keep folks from following your bad/incorrect advice.

The OP posted they were using Debian...so you posted a link to five year old instructions, and gave them things to type in/configure for Lubuntu 14.04??? What, exactly, addresses the OP's problem with Debian 7/8 there? Especially since what you posted is not only old, but not applicable to a current Debian? From the LQ Rules:

• Do not post if you do not have anything constructive to say in the post.
• When posting in an existing thread, ensure that what you're posting is on-topic and relevant to the thread.

Pepperflash instructions for Debian were easy to find, and provided to the OP. Shadow_7 provided a link to the generic .deb package for Debian derivatives (and a current one). Neither of these things require editing files that aren't there, or pointing someone to old instructions for something they didn't ask about.

As said, report what you'd like; you're giving bad advice, period. You continue to do so, despite being asked not to. No amount of or is going to change that. Think I'm wrong? Then post something that shows it....correct the information presented, so everyone can learn. Because until you do that, the only harsh truth is "If you don't want to be corrected, don't say things that aren't correct".

Shadow_7 posted what may be the best answer.

Do not add to the thread or engage in any fights that detract from the topic.
