Guest Ubuntu version override doesn't appear to work

I tried to override the Ubuntu version for the guest creation, but it appears the exported variables are not working. Here I tried to create a guest with Ubuntu 23.10, but it still used 24.04.

sdp@sdp:~/dx/guest-tools/image$ git checkout noble-24.04
Switched to branch 'noble-24.04'
Your branch is up to date with 'origin/noble-24.04'.
sdp@sdp:~/tdx/guest-tools/image$ git branch
  main
* noble-24.04

sdp@sdp:~/tdx/guest-tools/image$ export OFFICIAL_UBUNTU_IMAGE="https://cloud-images.ubuntu.com/releases/mantic/release/"
export CLOUD_IMG="ubuntu-23.10-server-cloudimg-amd64.img"

sdp@sdp:~/tdx/guest-tools/image$ echo $OFFICIAL_UBUNTU_IMAGE

2 things here:

  • sudo -E ./create-td-image.sh instead of sudo ./create-td-image.sh . This will be addressed in a coming merge request
  • for now, the guest image creation scripts on 24-04 branch cannot generate image for 23.10, please use the main branch to generate a 23.10 guest
