I also realized that since Debian has let the broken installer twist in the wind for a while, a user could use deb-multimedia's flashplayer-mozilla package, or flashplayer-chromium for PPAPI pepperflash, which actually contains and installs the plugin instead of downloading it from Adobe. They can do this because they don't care about getting any permission from Adobe to redistribute it, something that most distros can't get away with legally. They are in DMO's non-free section, and the beginner should be wary of installing other multimedia programs from there before backing up their system first. The Flash packages are safe to install from a technical standpoint, though.
