问题中报告的错误消息仅出现在 20.04 中。这里有一个解决方法。
启动到恢复模式并等到 cryptswapfile 加载超时。
转到根 shell（恢复菜单中从底部开始的第二个条目）并注释掉以下行，
/etc/fstab并在/etc/crypttab每行前面加上一个#字符。/etc/fstab：/dev/mapper/cryptswap none swap defaults 0 0/etc/crypttab：cryptswap /cryptswapfile /dev/urandom swap,cipher=aes-xts-plain64,size=256跑步
swapoff -a && update-initramfs -u。取消注释 fstab 和 crypttab 中注释掉的行，然后使用 重新启动
sudo reboot。

对于具有类似消息的人，但也谈论将设置为错误 UUID 的 RESUME 变量：
只需删除 initramfs-tools () 的恢复文件中自动设置的 RESUME 变量sudo rm /etc/initramfs-tools/conf.d/resume，或者将其更新为交换分区的正确 UUID。
