opkg update failed on Arduino Yun

Hi,
I've had similar results (see below). Trying to install node.js.
Could not attach the .sig files in /etc/opkg

FYI: I'm in California. Have plans to demonstrate node.js to
the local node.js community in San Francisco, California
next month. Likely, Joyent & pubnub people will likely be in the room.

Thanks, back to lunch
