这里没有太多关于 Linux 或数据库的知识，但在家庭测试台上，我尝试使用本教程在 Ubuntu Desktop 20.04 上安装 influx v2，其中我可以一路走到第 8 步。
我这边检查状态如下：
ben@ben-HP-ProBook-6550b:~/Desktop$ systemctl status influxdb

如果我执行教程中的第 9 步，我会收到此身份验证提示：
ben@ben-HP-ProBook-6550b:~/Desktop$ systemctl enable influxdb
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-unit-files ===
Authentication is required to manage system service or unit files.
Authenticating as: ben,,, (ben)

当我输入我的用户名密码ben并输入两次时：
==== AUTHENTICATION COMPLETE ===
==== AUTHENTICATING FOR org.freedesktop.systemd1.reload-daemon ===
Authentication is required to reload the systemd state.
Authenticating as: ben,,, (ben)
Password:
==== AUTHENTICATION COMPLETE ===
然后假设我可以进入教程步骤 10 中的下一步，influx setup再进行几个身份验证步骤，我在命令提示符上返回了 404。有什么想法可以尝试吗？
$ systemctl enable influxdb
