Hehe, that would work, apparently you should probably update every day because some times untested and broken software slips out.
"One of the sysadmins that was released was messed up. Including wiping out /etc/resolve.conf which is your dns resolver."
(oops , if you where unlucky as you where , someone shot someone in the foot, you are hosed from updating anything until you manually fix that maybe you should only update after Sangoma says it is stable )
But the good thing is now it has been fixed.
