    Point taken. But here's why I'm irritated. It's a vague question. Plus, he clearly didn't try searching.

    Solution (based on your vague question):

    Check /etc/hosts

    Tested with todays hardy and found the same problem.

    I added the DNS domain using Network Manager Applet and after that sudo won't work.

    [in /etc/hosts]

    Original:
    127.0.1.1 ubuntu

    After Network Manager:
    127.0.1.1 ubuntu.test.com

    sudo: unable to resolve host ubuntu
