我在 ubuntu 18.04 上通过 devstack 安装了 openstack。我卡在“无法启动 rtslib-fb-targetctl.service”，有人知道如何解决吗？

我只看到一件事是不正常的：你需要在服务中使用绝对路径，因此选择一个编辑器并更改mkdir为/bin/mkdir
可以使用以下方法进行编辑：
sudo nano /lib/systemd/system/rtslib-fb-targetctl.service
（或 vi、vim 或 gedit）
然后使用以下方式检查服务
systemctl status rtslib-fb-targetctl.service
如果它有效，请重新加载或停止/启动它
