W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://deb.torproject.org precise InRelease: The following signatures were invalid: KEYEXPIRED 1346668560 KEYEXPIRED 1346668560 KEYEXPIRED 1346668560 KEYEXPIRED 1346668560
That's because the subkey for deb.torproject.org expired, and you don't have the deb.torproject.org-keyring package installed.
Probably the simplest fix is to follow the instructions at https://www.torproject.org/docs/debian.html.en#ubuntu again, i.e., re-fetch and re-add the key. Then apt-get install the keyring this time too.
