Title:
  kubuntu-devel-release-upgrade crashes with TypeError

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Confirmed

Bug description:
  I was upgrading from 14.04 to 14.10. After a while, I got the
  following exception:

    File "/tmp/ubuntu-release-upgrader-opo6yaru/DistUpgrade/DistUpgradeViewKDE.py", line 337, in conffile
      os.write(self.master_fd, "y\n")
  TypeError: 'str' does not support the buffer interface

  Here's the full output:
