Comment 22 for bug 2058511

I was hit with this problem trying to install Ubuntu 24.04 alongside an existing Linux Mint deployment tonight. Annoying but it looks like some people have had success with using autoinstall.yaml.

Perhaps someone could please provide a bit of assistance for me and my existing configuration:

What should I be doing to have a safe/sane autoinstall.yaml for my scenario where I want:

* All partitions to be left as is (not reformatted) except the new vgsystem-ubroot
* UEFI bootloader to go in nvme0n1p1
* Grub, initfs, kernel etc to go in nvme0n1p5
* Ubuntu to be installed in vgsystem-ubroot at "/"
* New user to be created in vgsystem-home at "/home/", leaving existing files

I've had a few tries in a VM but I'm getting it wrong every time, so if someone has the required insight, please help.
