It would be lovely to see the *entire* error message, in case some part of it identifies the program that produced the error. Many messages do. Failing that, let's go out on a limb and guess that it's *your own* hostname that can't be resolved. What is the output of the "hostname" command? What is the output of "grep -F $(hostname) /etc/hosts"? What is the output of "grep hosts /etc/nsswitch.conf"?
