I'm going to dup this to LP: #1250817 for the FileNotFoundError
handling.  As far as the switch to wifi, that's not really something
that system-image has anything to do with.  It relies on ubuntu-
download-manager for handling things at that layer.

** Summary changed:

- Doesn't switch to wifi when checking for updates and/or doens't timeout
+ Doesn't switch to wifi when checking for updates and/or doesn't timeout

** This bug has been marked a duplicate of bug 1250817
   FileNotFoundErrors coming from u-d-m should result in UpdateAvailableStatus with an error_reason

Bug description:
  Hi there

  This is a more advanced use case, so I'd rate this medium severity.

  I have trouble with data connection on my phone, I dont think it works
  at all; I returned home where I have wifi and after a while I tried to
  get OS updates, which spinned "forever".

  First, it should not spin forever if data doesn't work, no idea what
  the timeout is, but it should be less than 30s (can't download an
  update sanely if you are not even able to check for an update in 30s).

  Then I forced connection to wifi (not sure why it didn't), it remained
  "checking for updates", I left the OS updates settings panel, and
  returned to it "checking for updates", forever and ever.

  I killed settings, went to OS updates, it was still stuck checking for
  updates.

  So this is probably all resolvable by applying proper timeouts and
  having a user-level retry option.

  There should be network timeouts in the service, and there should be a
  way to cancel the checks.

  I'm open to other suggestions on how to deal with this better, but it
  seems the only option here is to reboot or perhaps to wait super long
  for system-image to suicide or for download-manager to timeout.

  Cheers,
