python - Elasticsearch 在对系统进行任何操作时出错？

Question

我已经安装了 Elasticsearch，现在由于我工作场所的其他人所做的一些更改，在更新、安装新包等任何操作期​​间不断弹出一些错误，而且 elasticsearch 无法正常工作。

附上安装新包的错误日志。

我什至从网上尝试了不同的解决方案，比如尝试从系统中完全删除 elasticsearch。

我遵循的步骤。

我重新启动了系统，但错误不断出现。

有人对如何解决这个问题有建议吗？

这个命令也没有给出任何内容

$ systemctl status systemd-sysctl.service
Failed to get properties: No such interface ''

此安装中的 systemd 是您的初始化服务吗？还有这是什么linux发行版？您的发行版是哪个版本？我目前认为您可能没有使用 systemd，但 elasticsearch 包以某种方式假设了这一点。

如果您在 elasticsearch repository 中打开错误报告，我将不胜感激有了以上所有信息，这保证了对 ES 方面的更多研究(免责声明:我是一名 ES 开发人员，并且热衷于解决这个问题 :-)。

此外:您可以尝试通过运行 dpkg -P elasticsearch 完全删除 elasticsearch 包。

此外，您可以尝试将 set -x 添加到 /var/lib/dpkg/info/elasticsearch.postinst 并运行 sh/var/lib/dpkg/info/elasticsearch.postinst 配置 获得更多的调试输出
