Hi everybody,
I want to install flashplugin, Ther is an error on md5sum,   I want  to skip it, I mean not check it.
I used the --force-all, but it failed


debian225:/home/bela/Desktop# dpkg --force-all    -i flashplugin-nonfree_9.0.48.0.0ubuntu1~7.04.1_i386.deb
Download done.

md5sum mismatch install_flash_player_9_linux.tar.gz

The Flash plugin is NOT installed.
