This question already has an answer here:

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:2 http://security.ubuntu.com/ubuntu yakkety-security InRelease

Distributor ID: Ubuntu

Release:    16.10

Of course the key Prompt in /etc/update-manager/release-upgrades is set to normal.

And do-release-upgrade -d leads to:

root@mysystem:~# do-release-upgrade -d
Checking for a new Ubuntu release
No new release found

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.

    You may be better off staying with LTS releases on servers. You should back up your data first, but you can try do-release-upgrade -d – Panther Jan 17 '18 at 15:37
  • No need to backup. There's nothing on this system (yet). But there should be soon: That's why an update is reasonable. And in three month I'd like to update from 17.10 to 18.04 and not from 16.10 to 18.04 if this is possible as that way I'd expect less difficulties - if any - than from 16.10 to 18.04. – Regis May Jan 17 '18 at 15:50

    If it is a fresh system, personally I would just do a fresh install of 17.10 . Faster and more reliable than an upgrade – Panther Jan 17 '18 at 15:56

    Small issue: 17.04 has gone end of life. Same for 16.10. There is no upgrade path. You should have sticked with 16.04 if it is a production server. It is an LTS for a reason ;) – Rinzwind Jan 17 '18 at 16:08

    I recently did the same. See the answer and its comments in askubuntu.com/questions/996768/… to get a hint. You do need some Python skills to manage the update Yakkety -> Zesty -> Artful. As the questions are all closed, I cannot elaborate further. – kap Jan 25 '18 at 21:03

First I would like to add that this is a hack, and problems may or may not arrise from doing this. I only tried this with Ubuntu Server 16.10.

I managed to upgrade from server release 16.10 to 17.10 by doing the following:

Open /etc/apt/sources.list :

vim /etc/apt/sources.list

Change all references from yakkety to artful:


Do an update and upgrade:

apt update && apt upgrade

Reboot the system.

  • You're right. That really is a hack. It might work, but you'll understand that I'll first attempt to get a more recent Ubuntu image before I'll attempt such a hack. Nevertheless thank you for sharing this idea. – Regis May Jan 17 '18 at 19:57

    This worked for me, I couldn't find a proper way to go from 16.10 to 17.10. No other tools let me go to 17.04 as an intermediate step either. – Ryan Jackman Jan 24 '18 at 2:19
  • This worked for me but had a lot of complications which had to be dealt with later. – Sandeep C Feb 27 '18 at 18:36

I highly doubt that it is really the EOL that's the problem here. I've upgraded VERY old versions without any problems A LOT. Usually (from my experience), simply the very next version is proposed. So Yakkety should be upgraded to Zesty by that tool - not immediately to Artful like stated in the error message.

Perhaps it is a temporary technical flaw due to the fact that 17.10 was suspended for a while due to it bricking Laptops. AFAIK this problem is resolved now but perhaps this is still some fallout of this incident. At least that'll explain why the tool wants to skip 17.10 altogether.

    You missed the point of the error message which is that yakkety can't be upgraded to zesty anymore because zesty has been EOL too since January 13, 2018. – karel Jan 18 '18 at 10:50
  • Ah, yes. You are indeed right. But: askubuntu.com/questions/996768/… – rgpublic Jan 18 '18 at 11:14

    Which error message? The only message is: There is no update path. Nevertheless other Ubuntu message recommends: Please Update. There is a contradiction. And furthermore: The assumption that EOL is causing this would imply that Ubuntu deliberately removed an update path in the mean while. I never heard of such an activity and it seems to be strange to do something like that. Correct me if I'm wrong but EOL typically only means: "We don't update the packages any more", but not "don't keep the rules for updating packages". – Regis May Jan 18 '18 at 15:28
