Can't install flashplugin.nonfree. ERROR: wget failed to download

[Han Soo Chang <hansoo77jp@gmail.com>]

Hi,

I recently installed debian squeeze, but I can't see youtube videos on
iceweasel.

$ sudo apt-get install flashplugin-nonfree

Above command ends with a following error message. (My sources.list has non-free
included)

ERROR: wget failed to download

More information might be available at:
  http://wiki.debian.org/FlashPlayer

I consulted the webpage, and googled, but could not get useful information.

I appreciate any help.

Thanks,
Han Soo
