Install Pepperflash In Chromium

Go to the Google Chrome Webpage and download the web browser for your processor architecture.
Unpack the deb package ( I used file-roller ) and go to the directory /opt/google/chrome/ .

Select Pepperflash and Extract.

Inside the directory Pepperflash there is a file libpepflashplayer.so .

As root :
mv libpepflashplayer.so /usr/lib/chromium/plugins

As root edit the file default in /etc/chromium and add this line :

CHROMIUM_FLAGS=" --ppapi-flash-path=/usr/lib/chromium/plugins/libpepflashplayer.so"

The whole file will look like this :

# Default settings for chromium. This file is sourced by /bin/sh from
# /usr/bin/chromium

# Options to pass to chromium
CHROMIUM_FLAGS="--password-store=detect"
CHROMIUM_FLAGS=" --ppapi-flash-path=/usr/lib/chromium/plugins/libpepflashplayer.so"

Restart chromium.

Check the setting at chrome:plugins in the address bar ( check +Details ) :
