Description
Trying to perform an unattended install of Ubuntu 22.04 Server AMD64 on an Intel CPU MacBook Pro 2011 and I am getting the error message below.
Setup:
- macOS 12.3.1 on MacBook Pro 2018 (with Intel CPU)
- VirtualBox 6.1.34
- Ubuntu Live Server 20.04 AMD64: ubuntu-22.04-live-server-amd64.iso
Serving up user-data and meta-data with a python server on port 3003, based on a Ubuntu Server doc called autoinstall-quickstart.
Getting the following error message:
VBoxManage: info: Preparing unattended installation of Ubuntu_64 in machine 'axxxxx' (b7e7ff1a-1f41-4320-8e9f-c84a2cxxxxxx).
VBoxManage: error: Failed to open '/isolinux/isolinux.cfg' on the ISO '/Users/sxxxxx/dev/vm/iso/ubuntu-22.04-live-server-amd64.iso' (VERR_PATH_NOT_FOUND)
VBoxManage: error: Details: code VBOX_E_FILE_ERROR (0x80bb0004), component UnattendedWrap, interface IUnattended, callee nsISupports
VBoxManage: error: Context: "ConstructMedia()" at line 1859 of file VBoxManageMisc.cpp
The files in the isolinux folder are no longer needed, because the server autoinstall is no longer based on the debian-installer (aka d-i), but rather it is based on Subiquity. Therefore, the VBoxManage unattended installer should not be looking for these. I'm afraid that this might require a VBoxManage upgrade or patch to support the new 'cloud-init' and 'curtin' with 'subiquity' based installer, unless someone can come up with a neat workaround or maybe a new unattended install template.
From browsing the source code under UnattendedTemplates/ubuntu_preseed.cfg that the template is entirely based on the debian-installer (ubiquity) and seems to have no knowledge of the new installer (subiquity).
See the source code under: /browser/vbox/trunk/src/VBox/Main/UnattendedTemplates/ubuntu_preseed.cfg on VirtualBox dot org.
Thanks in advance!
It seems that VirtualBox is attempting to use an outdated unattended installation template based on the Debian installer (ubiquity) instead of the new Subiquity system for moto x3m Ubuntu 22.04.
