Ubuntu 20.04 clevis-luks 设置自动解锁不起作用

我有一台 Ubuntu 20.04 机器设置,我正在尝试配置它以进行磁盘加密。我正在尝试设置自动解锁,但我的配置到目前为止还不起作用,并且总是提示我输入密码。

为此,我按照以下步骤操作:

  1. sudo apt-get updatesudo apt-get install cryptsetup
  2. 检查 /dev/nvme0n1p3 -> sudo cryptsetup luksDump /dev/nvme0n1p3-> 没有令牌或键槽
  3. 安装clevisclevis-luksclevis-dracutclevis-udisks2clevis-systemdclevis-tpm2
  4. sudo clevis luks list -d /dev/nvme0n1p3-> 空
  5. echo <my password> | sudo clevis luks bind -d /dev/nvme0n1p3 tpm2 '{ "pcr_bank":"sha256", "pcr_ids": "7,11" }'
  6. sudo dracut -fv --regenerate-all
  7. 检查sudo clevis luks list -d /dev/nvme0n1p3->1: tpm2 '{"hash":"sha256","key":"ecc","pcr_bank":"sha256","pcr_ids":"7,11"}'
  8. lsblk -o NAME,UUID,MOUNTPOINT->
├─nvme0n1p1                 <uuid1>                              /boot/efi
├─nvme0n1p2                 <uuid2>   /boot
└─nvme0n1p3                 <uuid3>   
  └─dm_crypt-0              <uuid4> 
    └─ubuntu--vg-ubuntu--lv <uuidd5>   /
  1. cat /etc/crypttab->dm_crypt-0 UUID=<uuid3> none luks

启动时,我没有注意到 cryptsetup、luks、tpm2 出现任何错误。谷歌搜索并检查其他问题,我也验证过:

  1. sudo systemctl enable clevis-luks-askpass.path
  2. update-initramfs -c -k all-> 运行成功

我的 fstab 文件实际上并未列出加密分区: cat /etc/fstab->

# /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>
# / was on /dev/ubuntu-vg/ubuntu-lv during curtin installation
/dev/disk/by-id/<Some id which I don't know the origin of> / ext4 defaults 0 1
# /boot was on /dev/nvme0n1p2 during curtin installation
/dev/disk/by-uuid/<uuid2> /boot ext4 defaults 0 1
# /boot/efi was on /dev/nvme0n1p1 during curtin installation
/dev/disk/by-uuid/<uuid1> /boot/efi vfat defaults 0 1
/swap.img   none    swap    sw  0   0

我也尝试过手动将分区添加到 fstab 但没有成功。

无论我尝试什么,它总是在启动时要求输入密码。

我可以做什么来解决这个问题?

我失踪了:clevis-initramfs需要安装。添加后,自动解锁器就起作用了。
