I created a cloud-init file and validated it using the following command:

cloud-init schema --config-file source-files/server/user-data

After including my cloud config file in an Ubuntu 22.04 ISO file, I modified other files in Ubuntu to make it use my user-data. However, when attempting to install the VM, I encountered the following error:

__init()__ missing 1 required positional argument: 'name'

Here is my cloud-init content:

  • That error doesn't appear to have anything to do with cloud-init. What is `subiquity`? – larsks Mar 24 '23 at 12:10

    Subiquity is not something that I knew or configured @larsks. I thought it is part of auto installation process as error says "subiquity/Filesystem/apply_autoinstall_config" at the beginning. Looking to Google, it's said that subiquity is Ubuntu Server Installer and it is the one executing cloud-init configuration. – kursattokpinar Mar 24 '23 at 12:20
  • Ah, thanks for that. I hadn't realized they had adopted cloud-init for driving automated installs like this. Have you succesfully tried out the examples from https://ubuntu.com/server/docs/install/autoinstall-quickstart? – larsks Mar 24 '23 at 12:40
  • @larsks, I have been able to get simpler configurations to function properly, but the problem arose when I tried configuring the storage component in a more intricate way. – kursattokpinar Mar 24 '23 at 13:16

You have an error in your storage configuration. All logical volumes must have a name, but you're missing a name: attribute in all of your lvm_partition blocks. Instead of:

- id: root-lv
  type: lvm_partition
  volgroup: ubuntu-vg
  size: 15%
  wipe: superblock
  preserve: false

You need something like:

- id: root-lv
  name: root
  type: lvm_partition
  volgroup: ubuntu-vg
  size: 15%
  wipe: superblock
  preserve: false

(And so forth for the rest of your logical volume definitions.)

I would argue that you should also report a bug against the installer: you should be receiving a more useful error message in this situation.
