do-release-upgrade cannot be re-run if errors during upgrade

[Jamie Strandboge]

I was following the instructions on ServerUpgrade, and during the download of packages, my internet connection went down. After it was back up, I tried to re-run 'do-release-upgrade -d' and got a 'No space left on device' error. After making room on the partition, I re-ran 'do-release-upgrade -d' and have the following error:

Checking for a new ubuntu release
Failed Upgrade tool signature
Failed Upgrade tool

Traceback (most recent call last):

    if not self.extractDistUpgrader():

    tar = tarfile.open(self.tmpdir+"/"+os.path.basename(self.uri),"r")
  File "/usr/lib/python2.5/tarfile.py", line 1139, in open
    return func(name, "r", fileobj)
  File "/usr/lib/python2.5/tarfile.py", line 1200, in gzopen
    fileobj = file(name, mode + "b")
IOError: [Errno 2] No such file or directory: '/tmp/tmpIqSV8h/gutsy.tar.gz'

There is no clear way on how to recover from this state.
