Bug Description

[Test Case]
1) run update-manager --no-update
2) click to upgrade
3) authenticate
4) see release notification
5) disable network
6) click upgrade
7) Observe traceback in terminal in which you ran update-manager --no-update

Traceback (most recent call last):
  File "/usr/bin/do-release-upgrade", line 152, in <module>
    fetcher.run()
  File "/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeFetcherCore.py", line 278, in run
    _("Fetching the upgrade failed. There may be a network "

    return error(self.window_main.window_main, summary, message)
AttributeError: 'NoneType' object has no attribute 'window_main'

With the version of the package from -proposed you should see a "Failed to fetch" error message.

Hello Brian, or anyone else affected,

Accepted ubuntu-release-upgrader into saucy-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/ubuntu-release-upgrader/1:0.205.6 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!
