- Can I skip over releases when upgrading? 16 answers
I'm confused. I just tried to upgrade a Ubuntu Server system from 16.10 to 17.10 .... Without success. All typical ways of updating such an Ubuntu system do not work.
do-release-upgrade tells me:
An upgrade from 'yakkety' to 'artful' is not supported with this tool. And
apt dist-upgrade simply tell me: Nothing to upgrade.
There are tutorials using both tools to upgrade to 17.04 which don't help as now 17.10 is already released. They - of course - advice exactly both ways described above but following them results in the strange situation I just described.
So the questions is:
- How can I upgrade to 16.10 to 17.10?
- Or at least: How can I upgrade 16.10 to 17.04 (so that I in consequence might be able to update to 17.10)?
Here's an example:
root@mysystem:~# apt update && apt dist-upgrade Hit:1 http://de.archive.ubuntu.com/ubuntu yakkety InRelease Hit:2 http://security.ubuntu.com/ubuntu yakkety-security InRelease Hit:3 http://de.archive.ubuntu.com/ubuntu yakkety-updates InRelease Hit:4 http://de.archive.ubuntu.com/ubuntu yakkety-backports InRelease Reading package lists...

Distributor ID: Ubuntu Description: Ubuntu 16.10 Release: 16.10 Codename: yakkety root@mysystem:~#
Of course the key
Prompt in /etc/update-manager/release-upgrades is set to
do-release-upgrade -d leads to:
root@mysystem:~# do-release-upgrade -d Checking for a new Ubuntu release No new release found root@mysystem:~#
Note: The question is: Why is there no update path at all? Even if 16.10 as well as 17.04 is not maintained any longer there should be an update path.
As moderators do not seem to understand either the questions or the answers and associate this question to a completely uncorrelated question and prevent providing a real answer, I don't see another way as to provide the answer here within the question.
Answer: There is no update path. That's the problem. Yes, it's the Ubuntu way to not provide an update path for non-LTS releases as soon there is even a single non-LTS release in between the current release and the most recent one. This renders non-LTS releases completely useless after two non-LTS release have been published. There is no official way of upgrading.
So you have two options:
a) Do a reinstallation with a more recent (LTS) version. This is the cleanest solution you can get.
b) Or do some manual work with risks involved following the recommendations provided in this answer here: Upgrade from Yakkety Yak (Ubuntu 16.10) when its End of Life
This question is - if at all - a duplicate of THAT question just mentioned.
