No log file causing error in startup

I have gotten the server to boot before, but when I went back one day, this error shows up refusing to allow the server to boot. I looked everywhere on what to do, but found nothing. I even wiped my drive, installed a fresh install of Ubuntu and re-did everything to no avail.

I tried making a mylog.log file, but that did nothing. I do not have a worlds file since it has not booted yet, but in my log file I did not put anything, which might be the problem. Any help would be appreciated.
