  [ Brian Murray ]
  * DistUpgrade/DistUpgradeCache.py: When calculating free space needed for
    mount points don't use a negative number as the buffer. (LP: #1786484)
  * fix more typos re RELEASE_UPRADER_ALLOW_THIRD_PARTY
  * DistUpgrade/DistUpgradeCache.py: When calculating free space needed for
    mount points don't use a negative number as the buffer. (LP: #1786484)
  * fix more typos re RELEASE_UPRADER_ALLOW_THIRD_PARTY
  * DistUpgrade/DistUpgradeController.py: When rewriting sources.list entries
    check to see if the source provides packages for the release to which the
    upgrade is occurring. If it doesn't the entry is disabled thereby
    improving upgrades with PPAs. (LP: #1807043)
  * do-release-upgrade: add a parameter to allow third party mirrors and
    repositories, additionally pass along the environmental variable
    RELEASE_UPGRADER_ALLOW_THIRD_PARTY via pkexec and sudo. (LP: #1807032)
  * DistUpgrade/DistUpgradeCache.py: improve messaging regarding failures to
    calculate the upgrade and suggest using ppa-purge if PPAs are an issue.
  * DistUpgrade/DistUpgradeCache.py: in the event there is a failure to
    calculate the upgrade provide information about the log files in
    /var/log/dist-upgrade. (LP: #1771387)

  * autopkgtest: Update dependency from gir1.2-webkit-3.0 to gir1.2-webkit2-4.0

Title:
  confusing error message with 'do-release-upgrade -d' and Prompt=lts

Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released
Status in update-manager package in Ubuntu:
  Fix Released
Status in ubuntu-release-upgrader source package in Bionic:
  Triaged
Status in update-manager source package in Bionic:
  New

Bug description:
  On a bionic system with Prompt=lts set in /etc/update-manager/release-
  upgrades, 'do-release-upgrade -d' fails with:

  $ sudo do-release-upgrade -d 
  Checking for a new Ubuntu release
  Upgrades to the development release are only 
  available from the latest supported release.
  $ echo $?
  1
  $

  The refusal to upgrade is correct, but the message it gives is
  incorrect and gives no hint how to fix.

  Since bionic is the latest release listed in https://changelogs.ubuntu.com/meta-release-lts *and* in https://changelogs.ubuntu.com/meta-release-lts-development, a more accurate explanation would be: 
     There is no development version of an LTS release available.
     To upgrade to the latest non-LTS development release, set Prompt=normal.
