We are working on resolving bug http://launchpad.net/bugs/1766890 which
results in a bad upgrade experience when people upgrade to Ubuntu 18.04.
There is a new version of the dist-upgrader in -proposed and we will be
testing it the next couple of days and plan on updating meta-release-lts
at the beginning of next week.

Hi lxuser.

What apt source do you have? I.e. What does `apt-cache policy` show?

Any news about this?

Yeah, I would just like to have an official 18.04 ISO I can use to restore my system.

I upgraded to 18.04 and everything is working fine for me. Not sure if it's offical though. 

The difference between official Dell pre-installed ubuntu and vanilla ubuntu from Canonical is the extra repositories that the pre-installed system is configured with. I have asked Dell for a description of the available repositories on https://www.dell.com/community/Linux-Developer-Systems/Description-og-of-Dell-repositories-for-ubuntu-distributions/m-p/6204895 so that you can post-install configure a vanilla system to become equivalent to a pre-installed system.

The request, however, has not been answered. :-(

Ubuntu 18.04 released in April 2018 and will be supported until April 2023.

Ubuntu 12.04's LTS period ended April 28, 2017, you can purchase an Ubuntu 12.04 Extended Security Maintenance (ESM) license. Unlike the newer versions of Ubuntu, these updates won't be free.

http://releases.ubuntu.com/18.04.2/

64-bit PC (AMD64) desktop image

64-bit PC (AMD64) server install image

Ubuntu 12.04 patches will be available only through the Ubuntu Advantage support plan. Prices start at $150 per year per server and $250 per year with a minimum of 10 virtual servers. The latter plan includes work week online and phone technical support. There's also a desktop plan, which will run you $150 per year per desktop with a minimum order of 50 desktops. These updates will be delivered in a secure, private archive available only to customers on a per-node basis.

ESM subscriptions will last for at least twelve months.

I hope this helps answer your question. I am a newb so this could be complete rubbish but I discovered this after reading your question and thought I would share. If you still have access to the the pre upgrade image the following might help

I created a recovery USB stick and in the root there is a file called prepackage.dell in there you will see the list. Some of these are in non core repos. You will need to register them....

Look in the /etc/apt folder to see what extra repositories have been configured. On my machine the extra are setup under folder /etc/apt/source.list.d there is a file describing each extra repository.

The signing keys also need to be registered. I have a single file with all registered keys. /etc/apt/trusted.apg

I have successfully copied these files to a vm and can now access these repositories, which include the Dell signed oem device drivers (for my machine and version). I think i had to run sudo apt update to refresh the repo cache. Alternatively you can use the software and update UI component 

In the UI component there is also a tab for Additional Device drivers

I hope that helps

Hi @DELL-Jesse L 

It's 2020 now

Do you have any news of an ISO image with Ubuntu 18.04 for XPS 13 9370?

Thank you!
