未能启动rtslib Failed tctl.service

Question

我在ubuntu18.04上通过dev堆栈安装openstack。我坚持“未能启动rtslib Failed tctl.service”，有谁知道如何解决这个问题吗？

这是rtslib fb- This tctl.service的内容。

我只看到一件不正常的事情:您需要在服务中使用绝对路径，所以选择一个编辑器并将mkdir更改为/bin/mkdir。

编辑工作可通过以下方式完成：

sudo nano /lib/systemd/system/rtslib-fb-targetctl.service

(或vi、vim或gedit)

，然后使用

systemctl status rtslib-fb-targetctl.service

如果它能重新加载或停止/启动它
