Cannot download adobe-flashplugin_10.1.53.64

[era]

Binary package hint: flashplugin-nonfree

Ran aptitude update, then sudo aptitude reinstall flashplugin-installer. (I had to "reinstall" because from dpkg's perspective, the package is installed, although it failed to install the actual plugin.)

vnix$ apt-cache policy flashplugin-installer
flashplugin-installer:
