Comment 19 for bug 281808

Just to verify: I see this same problem on 9.04 (Jaunty alpha 4). I can fix it by doing a simpler version of what jartsa suggests above.

1) Go to adobe, and get the deb for ubuntu 8.04+, save locally

2) sudo dpkg --install install_flash_player_10_linux.deb

3) Then get the fp9 archive as suggested, from http://fpdownload.macromedia.com/get/flashplayer/installers/archive/fp9_archive.zip

4) Unzip, then cd to fp9_archive/9r152 (The highest numbered version)

5) tar xvfz flashplayer9r152_linux.tar.gz

6) sudo chown root.root libflashplayer.so

7) sudo mv libflashplayer.so /usr/lib/adobe-flashplugin/

This quietly replaces flash 10 with flash 9, and I believe you could uninstall it if you wanted using dpkg. I see that it now works in Konqueror
