This only started happening today, and I did nothing unusual, so I can't figure out why. I checked for updates a few hours ago via the command line with
sudo apt-get update and then repeatedly attempted to see if the issue was resolved using Synaptic (simply by clicking the "Reload" button). Every time I received some variation on the following:

I proceeded to use Y PPA Manager's "Try to Import All Missing Keys" feature, but that did not work, and the error messages still show up whether reloading through Synaptic or doing an apt-get update in the terminal. Can the knowledgeable amongst you please chime in?
P.S. I am running Xubuntu 14.04.
