最近，我重新安装了 kubuntu（来自 linux mint），还加密了驱动器和交换文件。启动时我收到错误：
Cryptsetup 等待加密的源设备 /swapfile。
经过一番搜索，我发现一个名为的命令sudo update-initramfs -u -k all应该可以解决这个问题。但是，我得到了一些无法解决的错误：
update-initramfs: Generating /boot/initrd.img-5.19.0-38-generic
cryptsetup: WARNING: cryptswap1: couldn't determine device type, assuming
default (plain).
cryptsetup: ERROR: Couldn't resolve device /swapfile

/etc/crypttab 文件的内容是cryptswap1 /swapfile /dev/loop0 swap,offset=1024,cipher=aes-xts-plain64,size=256
该命令lsblk -f给出以下内容：
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
loop0 swap 1 7ab8406f-ea13-4984-8211-b9dd27a0677c
└─cryptswap1 swap 1 cryptswap1 4cd157f7-3d8d-4893-aea8-be54200244e1 [SWAP]
有人能帮我吗？我可能与 crypttab 文件有关，但我不知道该更改什么。
