I had already downloaded and installed Flash for Firefox,
following these instructions
but could not get it to work as a plugin on Chromium.
Success is yours when you type "about:plugins" into the location bar of
Chromium and the Flash player appears.
Fortunately, it turned out to be pretty simple to just link Firefox's
plugin into Chromium: As root, do this:
ln -s /usr/lib64/mozilla/plugins-wrapped/nswrapper_32_64.libflashplayer.so .
1) Add the backports repository by editing /etc/apt/sources.lst
(must be root) and adding the following line:
deb http://www.backports.org/debian/ lenny-backports main contrib non-free
Run the following:
#aptitude install debian-backports-keyring
(Ignore any warning that occur with the above 2 commands, the install
will correct those) If you run #aptitude update again the warnings
should be gone
2) Install Adobe Flash
#aptitude install flashplugin-nonfree
3)You shouldn't need this step, but just in case run
and make sure the correct one
(/usr/lib/flashplugin-nonfree/libflashplayer.so) is selected. It should
be the current default.
4) Start Iceweasel and go the location about:plugins and you should see
the latest Flash.
