This bug was fixed in the package ubuntu-release-upgrader - 1:18.04.30
---------------
ubuntu-release-upgrader (1:18.04.30) bionic; urgency=medium
* data/release-upgrades: Clarify documentation regarding the behavior for
different Prompt settings. (LP: #1795024)
* do-release-upgrade: Utilize information regarding what Prompt is set to so
that a more informative error message can be displayed.
(LP: #1798618, LP: #1795024)
* 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)
* debian/source_ubuntu-release-upgrader.py: Include xorg_fixup.log if it
exists.
* DistUpgrade/xorg_fix_proprietary.py: modify how the system is checked to
see if nvidia is being used, drop fglrx check since it has been
deprecated. (LP: #1773637)

Bug description:
Impact
------
If Prompt=never in /etc/update-manager/release-upgrades and do-release-upgrade is run a likely confusing message regarding no new release being found is returned. This is can be a lie and doesn't help people upgrade if there is in fact a new release.
Test Case
---------
1) set Prompt=never in /etc/update-manager/release-upgrades
2) run 'do-release-upgrade' on 18.04 and also run 'do-release-upgrade -d' on 18.10
Observe an error message regarding no new release being available or
for the -d case on 18.10 one regarding upgrades to the dev release
only being supported from the latest supported release.
With versions of update-manager and ubuntu-release-upgrader (which
depends on the changes in update-manager) from -proposed you will
instead see a message about prompt being set to never and the file to
modify so you can upgrade.
Additionally, release-upgrades has been modified to indicate that use
never won't allow you to upgrade and to clarify what happens if you've
set lts on a non-lts release.
Original 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?
