无法启动 fwupd-refresh 服务

Question

我在多个 ubuntu 20 和 22 服务器上使该服务处于失败状态，这很烦人，因为它在我的监控系统上触发警告。

\n

我无法启动该服务，这是journalctl -xe我尝试启动它时的情况：

这是service fwupd-refresh status：

我不知道在哪里可以找到更多日志来了解这个问题，有什么想法吗？

编辑下面的文件

/lib/systemd/system/fwupd-refresh.service

添加 User=root，这解决了服务失败的问题。

然后：

systemctl daemon-reload; service fwupd-refresh restart; service fwupd-refresh status

这是服务文件的示例。
