It looks like there are timeouts from some of the keyservers. I’ve trimmed the 
list again to only servers known to be working (ubuntu and sks-keyservers.net 
<http://sks-keyservers.net/>). Can you give it a try again?

Brian, there are also a number of timeout errors related to central, but I 
think they are unrelated.

com.sonatype.central.secure.nexus.plugin.internal.AuthtokenFetcherImpl - Failed 
to fetch authtoken: org.apache.http.conn.ConnectTimeoutException: Connect to 
secure.central.sonatype.com:443 [secure.central.sonatype.com/207.223.241.90] 
failed: connect timed out
