md5sum mismatch install_flash_player_9_linux.tar.gz
The Flash plugin is NOT installed.

After some tinkering with the source itself, I patched it on my own system
It seems that the upstream file (install_flash_player_9_linux.tar.gz) has different md5sum with the one in debian/config and debian/postinst file.
It also has different content, where the previously install_flash_player_9_linux/flashplayer.xpt file is no longer exist, replaced with install_flash_player_9_linux/flashplayer-installer.
After patched and rebuild the source, flash is now working on my pc.
I only modified the config and postinst file

I have the same problem. There was Adobe Flash update on the official site, but the Ubuntu package only knows checksum for it's previous version. Manual installation works good, but i have a problem while playing h.264 video like this: http://marcelfahle.com/video/h264/bonifacio400kbits/ It's just some h.264 codec sample, and the video is flickering, does your also?

[SV (sv22342)]

OK, It looks like this flickering is not a bug, but rather some kind of intended effect :) The logo in the upper right corner on the video is not flickering, is it possible to intentionally create such a effect? ;)

But the installation problem of course is a real thing, so many people will be pissed off.
