It appears the public key for the precies-security and precise-updates
package isn't available during the update. Adding it manually with
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv

worked for all but one package, java-package, which I simply removed.

Public bug reported:
The 9755 nvidia driver includes a new file called libnvidia-

and libwfb.so.1. These files are not included in the linux-restricted-
modules package.
