Comment 4 for bug 1223894

The tarball was there, plus a bunch of files. Extracting the files appeared to complete successfully.

I renamed ubuntu-release-upgrader-vijh2f to asdf and re-ran "update-manager -d". It crashed at the same point, slightly differently:

$ sudo update-manager -d
Checking for a new Ubuntu release
authenticate 'saucy.tar.gz' against 'saucy.tar.gz.gpg'
extracting 'saucy.tar.gz'
Real-time signal 0

I diffed the old directory against the new one, to see if the second extraction had completed successfully:
l# diff . ../asdf -r
diff: ./demoted.cfg: Too many levels of symbolic links
diff: ../asdf/demoted.cfg: Too many levels of symbolic links
diff: ./DistUpgrade: recursive directory loop
Binary files ./DistUpgradeApport.pyc and ../asdf/DistUpgradeApport.pyc differ
Binary files ./DistUpgradeAufs.pyc and ../asdf/DistUpgradeAufs.pyc differ
Binary files ./DistUpgradeConfigParser.pyc and ../asdf/DistUpgradeConfigParser.pyc differ
Binary files ./DistUpgradeGettext.pyc and ../asdf/DistUpgradeGettext.pyc differ
Binary files ./DistUpgradeMain.pyc and ../asdf/DistUpgradeMain.pyc differ
Binary files ./DistUpgradeVersion.pyc and ../asdf/DistUpgradeVersion.pyc differ
Binary files ./DistUpgradeViewGtk3.pyc and ../asdf/DistUpgradeViewGtk3.pyc differ
Binary files ./DistUpgradeView.pyc and ../asdf/DistUpgradeView.pyc differ
Binary files ./__init__.pyc and ../asdf/__init__.pyc differ
Binary files ./SimpleGtk3builderApp.pyc and ../asdf/SimpleGtk3builderApp.pyc differ
Binary files ./trustdb.gpg and ../asdf/trustdb.gpg differ

Since the tarball didn't include any pyc files, I deduce that the tarball was completely extracted and the crash happened when trying to run or compile the extracted files.
