Title:
  do-release-upgrade crashes if any directories exist in
  /etc/apt/sources.list.d

Status in “apt-clone” package in Ubuntu:
  New

Bug description:
  This has happened to me on two different machines now when attempting
  to upgrade from 12.04 to 12.10.  I usually make a backup of my
  sources.list.d/*.list files in a subdirectory e.g.
  /etc/apt/sources.list.d/old.  Every time I tried to do the release
  upgrade (from Software Updater) I got the message that "do-release-
  upgrade has closed unexpectedly" without any further information.  I
  finally discovered the cause in /var/log/dist-
  upgrade/20121028-2325/main.log:

    File "/tmp/update-manager-qYs_K9/quantal", line 10, in <module> sys.exit(main())
    File "/tmp/update-manager-qYs_K9/DistUpgrade/DistUpgradeMain.py", line 237, in main save_system_state(logdir)
    File "/tmp/update-manager-qYs_K9/DistUpgrade/DistUpgradeMain.py", line 130, in save_system_state scrub_sources=True)
    File "/tmp/update-manager-qYs_K9/DistUpgrade/apt_clone.py", line 148, in save_state self._write_state_sources_list(tar, scrub_sources)
    File "/tmp/update-manager-qYs_K9/DistUpgrade/apt_clone.py", line 235, in _write_state_sources_list "./etc/apt/sources.list.d/"+source)
    File "/tmp/update-manager-qYs_K9/DistUpgrade/apt_clone.py", line 239, in _add_file_to_tar_with_password_check with tempfile.NamedTemporaryFile(mode='w') as source_copy, open(sources, 'r') as f:
  IOError: [Errno 21] Is a directory: '/etc/apt/sources.list.d//old'

  Moving /etc/apt/sources.list.d/old out of the way allowed the upgrade
  to proceed successfully.  Like I said, I observed this same behaviour
  (and the solution) on two different machines.  Should be an easy fix
  to check if those files are directories or not before trying to add
  them to the tar file.
