未来设置的超级块，修复系统时钟

我不断收到有关我的超级块挂载时间在未来的错误消息，并坚持在每次启动时执行 fsck，而且我每次都必须从恢复选项中进入来执行此操作。

以下是我认为可能有帮助的信息，我在启动和 fsck 后运行了这些信息：

我尽快用一个字符串运行了第二次：

答案1

可能是你的 BIOS 电池坏了。这似乎在某些旧笔记本电脑型号中很常见。更换电池可能会解决问题。另一个对我有用的解决方案是告诉 e2fsck 你的时钟坏了：

将以下内容放入/etc/e2fsck.conf：

[options]
broken_system_clock = true

然后你必须把这个 conf 文件添加到你的 initramfs 中。
将以下内容放入/etc/initramfs-tools/hooks/e2fsck-conf.sh：

#!/bin/sh

PREREQ=""  
prereqs()
{
   echo "$PREREQ"
}

case $1 in
prereqs)
   prereqs
   exit 0
   ;;
esac

. /usr/share/initramfs-tools/hook-functions
CONFFILE=/etc/e2fsck.conf
CONFDIR=`dirname "$CONFFILE"`
if [ -f "$CONFFILE" ]
then 
   mkdir -p ${DESTDIR}${CONFDIR}
   cp $CONFFILE ${DESTDIR}${CONFDIR}
fi

然后执行sudo update-initramfs -u。

答案2

答案似乎已经确定这里

Ctrl基本上，用+ Alt+启动终端T。然后输入。

sudo apt-get install ntp

安装完成后，使用以下命令启动服务：

sudo service ntp start
