[Bug 1076186] Re: not possible to upgrade to raring

[ConMotto]

I'm still getting this on a fully updated 12.10 server x64 install. :(

# do-release-upgrade 
Checking for a new Ubuntu release
Traceback (most recent call last):
  File "/usr/bin/do-release-upgrade", line 145, in <module>
    fetcher.run_options += ["--mode=%s" % options.mode,

Error in sys.excepthook:

OSError: [Errno 2] No such file or directory: '/var/crash/_usr_bin_do-release-upgrade.0.crash'

Original exception was:
