I was trying to upgrade from 12.04 to 14.04. After upgradation I could not enter normal boot. So I went into rescue mode and tried to update. The laptop went into hibernate mode. I could not restart in normal mode. So once again I went into rescue mode and tried update but I could not. I get the following error message when I try to update now.
