  * 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)

Title:
  setting release-upgrades Prompt to never can cause confusing behavior

Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released
Status in update-manager package in Ubuntu:
  Fix Released

Bug description:
  The prompt setting in /etc/update-manager/release-upgrades controls
  whether the user is prompted to upgrade, but also controls whether the
  user can manually upgrade using do-release-upgrade -d.

  Steps to reproduce:
  1) On an 18.04 machine, set Prompt in /etc/update-manager/release-upgrades to lts or never.
  2) Attempt to upgrade to 18.10 beta using do-release-upgrade -d.  
  3) The upgrade reports "Upgrades to the development release are only available from the latest supported release."  This is both an incorrect error message, and it prevents upgrade even though the user has specifically requested the development version.

  Possible fixes:
  1) The documentation should be changed to indicate that the Prompt argument controls both whether you are prompted to upgrade, but also whether you can use the upgrade tool at all.
  2) A second configuration option should be added to allow the admin to control the prompting for upgrade separately from the ability to upgrade, allowing users to upgrade the system manually, even when Prompt is set to never.

  Question:  Is the default setting of Prompt=lts going to prevent users
  from upgrading their 18.04 machines to 18.10 until they change it to
  normal?

  Description:    Ubuntu 18.04.1 LTS
  Release:        18.04
