我是一名 Ubuntu 新手用户，按照本教程在运行 Ubuntu 18.04 的 Mac Mini 4.1 上使用mbpfan启用风扇管理。
我最初取得了很好的成功，然后尝试将mbpfan变成系统服务。我遇到的第一个问题是安装后我的系统上没有 mbpfan.service 文件，所以我只是从 GitHub下载它，通过 SFTP 将它上传到我的下载文件夹，然后按照指示复制它sudo cp mbpfan.service /etc/systemd/system/。
但这是我尝试执行时的结果sudo systemctl enable mbpfan.service：
Synchronizing state of mbpfan.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable mbpfan
Failed to enable unit: File mbpfan.service: Invalid argument
我有点卡在这一点上，希望能轻推一下。谢谢你。
