启动时，我收到以下两条消息：
[FAILED] Failed to start LSB: Start NTP daemon.
See 'systemctl status ntp.service' for details.
[FAILED] Failed to start Cryptography Setup for sda7_crypt.
See 'systemctl status systemd-cryptsetup@sda7_crypt.service' for details.
[DEPEND] Dependency failed for Encrypted Volumes.
但是启动计算机后 NTP 似乎正在运行，并且我的 sda7_crypt 卷确实已安装。
$ systemctl status ntp.service

那么为什么我的计算机显示失败？
