I have downloaded oceanbase-all-in-one package.

wget https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/download-center/opensource/oceanbase-all-in-one/8/x86_64/oceanbase-all-in-one-4.2.2.0-100010012024022719.el8.x86_64.tar.gz

I used the CentOS 8 Docker image and followed your instructions but couldn't reproduce the issue. It might be an environmental problem. You could try uninstalling oceanbase-all-in-one and then reinstalling it, or alternatively try it on a different machine.

Could you package and provide the complete logs of OBD for further analysis? The log directory is: ~/.obd/log/.

我全部删除干净，换了一个安装目录后，重新安装就成功了。 当时没有保留任何全量日志。

不过看报错信息，应该还是哪里的 Python 代码判断有问题，建议参考我在反馈中采集到的错误堆栈信息（generate_config.py 文件第350行报错），应该能够逆向分析出导致出错的各种源因。

The unexpected error may have been caused by plugin upgrades or other environmental issues. Currently, it is not reproducible and cannot be precisely pinpointed. If similar issues occur in the future, please retain the complete logs, configurations, and operating system information.
