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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1223894 Title: Segfault trying to upgrade to saucy from raring To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1223894/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
