Title:
  subiquity/curtin install failed on Resolute Snapshot 4

Status in curtin:
  New

Bug description:
  I have a working auto install for Ubuntu 24.04 Noble, which I am
  attempting to get working using today's Snapshot 4 Release -
  ubuntu-26.04-snapshot4-live-server-amd64

  Instead it fails with a python error - Module Not Found curtin.vendor

  See the attached photo from my PC

  I was testing using a KVM virtual machine:

  truncate -s 4T /tmp/disk.img

  kvm -no-reboot -m 2048 -drive
  file=/tmp/disk.img,format=raw,cache=none,if=virtio -cdrom
  /home/david/Downloads/iso/ubuntu-26.04-snapshot4-live-server-amd64.iso
  -kernel ubuntu-resolute-snap4-kernelimage         -initrd ubuntu-
  resolute-snap4-initrd -append 'autoinstall ds=nocloud-
  net;s=http://_gateway:3003/'

  Where the kernel and initrd where obtained by mounting the ISO image
  and copying them from the casper directory.

  In another tab I served the curtin configuration files with:
  python3 -m http.server 3003
