[Bug 1310851] Re: Failed to fetch window does not appear

[Chris Halse Rogers]

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!

** Changed in: ubuntu-release-upgrader (Ubuntu Saucy)
       Status: In Progress => Fix Committed

** Tags added: verification-needed

  [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 "

  "Failed to fetch" error message.
