** Description changed: [ Impact ] Heat templates that include MIME type `x-shellscript` user-data fail due to an incorrect shebang in loguserdata.py [1]. This failure prevents use of `x-shellscript` user-data in heat templates [2]. [1] https://review.opendev.org/c/openstack/heat/+/916058 [2] https://docs.openstack.org/heat/latest/template_guide/software_deployment.html [ Test Plan ] Deploy OpenStack Caracal. As Charmed Openstack Caracal does not support Noble as a base, deploy Jammy/Caracal and DRU the heat unit to Noble to test the Noble package. Create a stack with this template: ```yaml heat_template_version: 2021-04-16 description: Deploy an instance with some user-data resources: - user-data-inst: - type: OS::Nova::Server - properties: - image: noble-server-cloudimg-amd64 - flavor: m1.small - key_name: heat_key - networks: - - network: private - - network: ext_net - user_data: | - #!/bin/bash + user-data-inst: + type: OS::Nova::Server + properties: + image: noble-server-cloudimg-amd64 + flavor: m1.small + key_name: heat_key + networks: + - network: private + - network: ext_net + user_data: | + #!/bin/bash - mkdir -p /usr/local/share/hello - echo "Hello, world!" > /usr/local/share/hello/hello.txt + mkdir -p /usr/local/share/hello + echo "Hello, world!" > /usr/local/share/hello/hello.txt ``` ``` os stack create -t user-data-template.yaml ud0 ``` Expected result: cloud-init succeeds and /usr/local/share/hello/hello.txt is created. Actual result: cloud-init fails: ``` Cloud-init v. 25.1.2-0ubuntu0~24.04.1 running 'modules:final' at Mon, 14 Jul 2025 13:59:07 +0000.
