I just had this happen to me on a fresh edgy install of a Lenovo T60. The network didn't come up during install (ipw3945 couldn't auto-detect the office wifi). So post-install, I brought the network up by pointing it at the right ESSID. At that point ntpdate helpfully slewed the clock by -28805 seconds and sudo promptly went onstrike on any existing ttys.
Either we shouldn't slew time so drastically or core system tools like sudo shouldn't break when we do. ** Changed in: sudo (Ubuntu) Status: Rejected => Confirmed -- Changing time could lock you out of the machine https://launchpad.net/bugs/24217 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
