Fedora 31 LXC服务未能启动“未能启动LXC的FUSE文件系统”

Question

我试图在Fedora工作站上设置用于测试环境的LXD系统，但是LXD服务由于依赖服务LXC失败而无法启动。在尝试启动sudo systemctl start lxd.service之后，journalctl -xe给出的错误消息是：

我对这件事很困惑。到目前为止，我一直遵循以下安装和配置步骤：https://copr.fedorainfracloud.org/coprs/ganto/lxc3/，但现在我陷入了服务启动失败的境地。我做错了什么？

您真的需要lxcfs服务吗？卸载它怎么样？

如果你确实需要这种服务，你应该关注为什么它不起作用。检查这些命令的输出：

journalctl -u lxcfs.service
systemctl cat lxcfs.service

在ExecStart部分中查找服务选项，然后尝试手动运行该命令。它显示屏幕上有什么错误吗？
