Usually Flash 10 should work in most Linux distros.
Installing version 10.1.53.64 is now advisable.
Flashplayer 9 in Linux is only necessary for distros with libc version < 2.4 .
For flashplayer 9.0.277.0 for Linux here the download address,
because it's hard to find :
from the site :
http://www.adobe.com/support/flashplayer/downloads.html
download "Linux Flash Player 9 Plugin content debugger"
or the direct link :
http://download.macromedia.com/pub/flashplayer/updaters/9/flashplayer_9_plugin_debug.tar.gz
If Flashplayer 10 does not work, watch if liblcms.so.1 is present in
/usr/lib/ , if it is not you can add it.
It is for example in
liblcms1_1.18.dfsg-1ubuntu1_i386.deb
for Ubuntu and its derivatives, or in
liblcms1_1.17.dfsg-1+lenny2_i386.deb
for Debian.
If you should want liblcms.so.1 alone, you can unpack the .deb
using the program "alien" to make a tar.gz with the command
alien -tc FILE
and unpack then the tar.gz package.
For distros using .rpm packages,
look here :
http://rpm.pbone.net/index.php3/stat/3/srodzaj/1/search/liblcms.so.1
Alien would also unpack .rpm's.
