更新SDK时，提示`curl: (22) The requested URL returned error: 503`

LCode

引用文档：https://wiki.t-firefly.com/zh_CN ... ux_compile_gpt.html

参照上述文档，输入执行如下命令更新SDK包时，命令输出中包含了如下`503`错误。
后续的编译顺利，生成的完整`iso`镜像运行暂未发现问题。
但好奇该错误是不是因有些库已经删除了？会有哪些影响？

执行的命令：
```
# filename: bm_sync.sh
.repo/repo/repo sync -l
.repo/repo/repo sync -c --no-tags
.repo/repo/repo start firefly --all

```

错误片段：
```bash
curl: (22) The requested URL returned error: 503
