启动时出错

Question

我三天前用 LXQT 安装了 Debian 10.3.0。这太棒了，我喜欢它，它启动得很好，启动时的每个内核行都非常好，当出现 2 条红线时，它们非常丑陋！

[OK] Started /etc/rc.local.
[26.409377] CIFS: Unknown mount option "umask=000"
[FAILED] Failed to mount /mnt/smb.
See 'systemctl status mnt-smb.mount' for details.
[DEPEND] Dependency failed for Remote File Systems.

我创建了 rc.local 来制作 ConnMan UI 来修复我的局域网卡以正常工作。因此，感谢 rc.local 它在启动时启动命令以使其正常工作。启动时的错误是由此更改引起的吗？一切正常，请告诉我如何修复此问题以实现 100% 干净启动。另外，当系统启动到达这条线时，它会减慢启动5秒。

文件 rc.local 包含

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

/sbin/ethtool -s ens5f5 speed 100 duplex full

exit 0

编辑#1这是的输出systemctl status mnt-smb.mount

systemctl status mnt-smb.mount

事实上，我曾尝试通过 LAN 将 Windows 与 Debian 连接起来，但没有成功。也许我的尝试产生了这个我不知道如何解决的问题！
