   我在运行hello world 的时候 会报一个空指针错误 ，我看了一下是由于 这个文件 不存在 导致 的
   `private final static String TEE_SDK_SIGNED_PACKAGE_PATH = "lib_tee_sdk_svm_load.signed";`
   请问这里还需要什么额外的步骤来生成这个对应 的文件 吗

   和UEFI应该没有关系，我们是可以在Ubuntu下安装SGX Driver的. sgx_enclave和sgx_provison不是两个目录，是两个driver文件. 您能把SGX Driver安装完成后的截图发给我们看看吗？或者您可以加入机密计算SIG钉钉交流群(42822683)，我们在群里交流效率更高.

   我换了一个 ubuntu的操作系统 ，就能把镜像 拉下来了，之前用的centos 7.9 就拉不下来，好像报 什么manifest error 之类 的。
   不过还想请教另外一个问题 呢？
   问题： 我照着 官方文档安装对应系统的driver 的时候 ，发现一直没有 sgx_enclave 和 sgx_provision 两个 目录 ，后来我看了一下阿里云官方上面 是需要 UEFI 版本的系统 , 按大佬们的经验，会是系统 的问题吗

   如果host选择Ubuntu确实会出现这个现象，应该是Teaclave Java TEE SDK存在Bug. 请选择Alibaba Cloud Linux 3.2104 LTS作为host os，这种配置下可以正常工作.

   不是在容器里面运行的，那个镜像虽然在docker hub 里面能搜到，但是拉不下来，我是直接运行的
