Проблема

После создания шаблона Ubuntu 20.04 (также попробовал 21.04) с помощью Packer я не могу установить новые настройки при создании экземпляра шаблона с помощью Terraform. У этой конфигурации не было проблем с Debian 10.

Ответ №1:

Проблема специфична для VMware vSphere. Чтобы исправить это :

 rm -rf /etc/cloud/cloud.cfg.d/subiquity-disable-cloudinit-networking.cfg
rm -rf /etc/cloud/cloud.cfg.d/99-installer.cfg
