问题：我按照说明使用 LUKS+LVM 在 EFI 系统上安装 Ubuntu 16.04这个的已投票 AskUbuntu 上的问题，但最终我的系统却无法使用。
我唯一改变的是分区的大小/顺序，以及执行分区的设备。
这是输出lsblk， 这磁盘感兴趣的是/dev/sdb/：

这lvm在里面卢克斯分区/dev/sdb3被称为crypt并包含交换，根和家。
剩余磁盘由Windows 10，所以我保持原样。
获得唯一标识来自/dev/sdb3块：

我/etc/crypttab按照说明在新系统内更新了文件：
crypt UUID="132a57e3-b7dd-4404-9782-944a050d3153" none luks
因为我希望每次都提示输入密码，所以我没有配置密码文件。
目前我的/etc/fstab/样子如下
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/mapper/vgcrypt-lvcryptroot / ext4 errors=remount-ro 0 1
# /boot was on /dev/sdb2 during installation

/dev/mapper/vgcrypt-lvcrypthome /home ext4 defaults 0 2
/dev/mapper/vgcrypt-lvcryptswap none swap sw 0 0
据我所知，该文件是在安装过程中自动生成的，并且看起来不错。
错误：
在启动过程中，我被带到忙碌箱出现以下错误消息：
Volume group not found
Cannot process volume group vgcrypt
到目前为止，我对这个错误感到有些困惑谷歌搜索在第一页的结果中似乎没有返回任何有用的答案。
问题：有人知道我的设置出了什么问题以及如何修复它吗？
我已经尝试过使用
# update-initramfs -u -k all
并证实lvm2安装在新系统中，Ubuntu 16.04与内核4.4.0-31-通用。

答案1
在 /etc/crypttab 中
crypt UUID="132a57e3-b7dd-4404-9782-944a050d3153" 无 luks
尝试不带引号的那行
crypt UUID=132a57e3-b7dd-4404-9782-944a050d3153 none luks
应该可以
