In the case that both the US and Europe mirrors are not responding, a workaround is to download the install_flash_player_7_linux.tar.gz from Macromedia's/Adobe's Web site (follow the Download-> Players links), purge flashplugin-nonfree, and reinstall flashplugin-nonfree making sure to answer "no" when prompted to download and install the plugin from the Internet. Afterward, issue:
$ sudo update-flashplugin --local-file $directory_containing_install_flash_player_7_linux.tar.gz (Note that --local-file accepts the directory, not the path of the actual file!) -- Hangs at Setting up flashplugin-nonfree https://launchpad.net/bugs/48620 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
