[Bug 1569324] Re: Update Manager shouldn't suggest 14.04 -> 15.10 unsupported upgrade path
** Description changed:
As far as I can see Ubuntu only supports 2 release upgrade paths[1]:
- 1. ${release} upgrade to ${next-release} (e.g. for 14.04 -> 15.10, you'll
have to 14.04 -> 14.10 -> 15.04 -> 15.10, 3 upgrades in a row)
- 2. ${lts-release} upgrade to ${next-lts-release} (e.g. for 12.04 ->
14.04, you can do a direct upgrade)
+ 1. ${release} upgrade to ${next-release} (e.g. for 14.04 -> 15.10, you'll
have to 14.04 -> 14.10 -> 15.04 -> 15.10, 3 upgrades in a row)
+ 2. ${lts-release} upgrade to ${next-lts-release} (e.g. for 12.04 ->
14.04, you can do a direct upgrade)
However currently on a ubuntu 14.04 if user chooses to "show any new
Ubuntu versions" Update Manager(and do-release-upgrade) will suggest to
directly upgrade to Ubuntu 15.10, this upgrade path has been verified[2]
to cause entire system hang during the upgrade process and even if you
- do a hard reboot you'll end in a console-only 15.10 environment.
+ do a hard reboot you'll end in a console-only 15.10 environment(UPDATE:
+ still fixable with a `# dpkg --configure -a` under console).
Update Manager/do-release-upgrade should instead follow the 14.04 ->
14.10 -> 15.04 -> 15.10 upgrade path, while using old-
releases.ubuntu.com[3] software source during the interim EOL'd ubuntu
release upgrade

[Bug 1569324] Re: Update Manager shouldn't suggest 14.04 -> 15.10 unsupported upgrade path
Hi Brian, I believe that the new upgrade behaviour/practice should also be documented/updated in the [General Upgrade Information section](https://help.ubuntu.com/community/UpgradeNotes) in the Ubuntu Wiki? > To avoid damaging your running system, upgrading should only be done from one > release > to the next release (e.g. Ubuntu 12.04 to Ubuntu 12.10) or from one LTS > release to the > next (e.g. Ubuntu 10.04 LTS to Ubuntu 12.04 LTS) Also I would like to re-confirm that the 14.04 -> 15.10 skip-release upgrade isn't (well, in best effort) considered to have migration issues(e.g. the Upstart -> Systemd conversion happens between 15.04 -> 15.10)? Like I previously mentioned above I did experience problems while attempting to perform the upgrade on a complete clean install[1].

That is incorrect actually and is documented in bug 1497024, the changes
happened in this version of update-manager.
update-manager (1:15.10.1) wily; urgency=medium
* UpdateManager/Core/MetaRelease.py: When not running in development mode,
if the next release is unsupported do not offer to upgrade to that, but
the release after it. When running in development mode continue to offer
upgrading to unsupported release. (LP: #1497024)
** Changed in: ubuntu-release-upgrader (Ubuntu)
Status: New => Invalid
