XPS 13 9360, Ubuntu 18.04 Upgrade procedure

I wonder the same. 

xzero@DELL-XPS-13-9360-DEV:~$ sudo do-release-upgrade
Checking for a new Ubuntu release
No new release found.

No luck with upgrade tool.

xzero@DELL-XPS-13-9360-DEV:~$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 16.04.4 LTS
Release:	16.04
Codename:	xenial

I have the same question.

Dell please push 18.04 to your new laptops or at least have an upgrade path with supported drivers.

I think the update will be provided after the release of 18.04.1

Okay, 18.04.1 is out.  I see new XPSs are coming out with 18.04.1.  https://betanews.com/2018/07/27/dell-xps-13-developer-1804-beaver/

How do I upgrade?  Thanks!

That worked!  :) I had it set to LTS only, which was blocking it.  Changing it like you said triggered the update notification for Bionic!  Thank you! :)))))

It was the case on my 9370 also. Obviously "LTS only" should be the right setting here, so it seems to be a "bug" IMO (?)

Since you're on 16.04, it's not a bug, as they are only just making the upgrade from 16.04 to 18.04 available, as you can read on https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes and https://linuxconfig.org/how-to-upgrade-to-ubuntu-18-04-lts-bionic-beaver

"Upgrades from 16.04 LTS will not be enabled until a few days after 18.04.1's release expected in late July."

You probably just have to wait a few days and it should become available :) (or switch to non LTS releases).

We are already late in July, and it was an upgrade from 16.04 LTS to 18.04.1 LTS on my 9370 :)

Any news on this? Am I stuck with Dell's 16.04.x?

I may be mistaken, but Dell's Ubuntu isn't anything different from normal, is it? Give it a couple of days maybe to roll out and tray again I'd say.

Waited a couple of days, tried again, but nothing...:

It's a little bit different actually. Apparently Dell optimizes Ubuntu for their laptops, and ensures that all drivers are properly installed. Even though I had initial issue with Ubuntu on this laptop, which nearly rendered it unusable, I fixed it, and ever since it's been most stable Ubuntu I ever used. 

Well, I got a message right now that an upgrade to the LTS 18.04 is available.

Haven't tried yet, though, because I cannot really afford time at the moment to fix any major problems that might occur.

Has anyone upgraded already?

Still not ready for me. However, this post (among others) explains how to upgrade before it lets you by default (not tried):
