我全新安装了 Ubuntu 24.04，其中有 ZFS 和由 Ubuntu 安装程序自动创建的 8GB 交换分区，如下所示/dev/nvme0n1p3。

我升级到 24.10，重启后交换分区不可用。似乎swapon找不到加密分区。升级过程中出了什么问题？

/etc/fstab自全新安装以来，我的未经修改：

# /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/disk/by-id/dm-uuid-CRYPT-PLAIN-dm_crypt-0 none swap sw 0 0
# Use `zfs list` for current zfs mount info
# bpool none defaults 0 0
# Use `zfs list` for current zfs mount info
# rpool none defaults 0 0
# Use `zfs list` for current zfs mount info
# rpool / defaults 0 0
# Use `zfs list` for current zfs mount info
# rpool none defaults 0 0
# Use `zfs list` for current zfs mount info
# rpool /root defaults 0 0
# Use `zfs list` for current zfs mount info
# rpool /home defaults 0 0
# Use `zfs list` for current zfs mount info
# bpool /boot defaults 0 0
# /boot/efi was on /dev/nvme0n1p1 during curtin installation
/dev/disk/by-uuid/6DA7-371B /boot/efi vfat defaults 0 1

还有我的/etc/crypttab：

dm_crypt-0 PARTUUID=d5018485-33be-40b8-80a1-9adb3c96ff16 /dev/urandom swap,initramfs

我尝试用/etc/crypttab替换 ID ，但重启后问题仍未解决。PARTUUID=d5018485-33be-40b8-80a1-9adb3c96ff16/dev/nvme0n1p3

我还尝试添加以下选项： swap,initramfs,plain,cipher=aes-xts-plain64,size=256

$ sudo blkid：（我没有显示许多循环设备）

另外，我不知道这是否相关，但在启动过程中，当提示输入（ZFS 加密）磁盘密码时，我收到以下警告： cryptsetup: WARNING: Option 'size' missing in crypttab for plain dm-crypt mapping dm_crypt-0. Please read /usr/share/doc/cryptsetup-initramfs/README.initramfs.gz and add the correct 'size' option to your crypttab(5).

username即使在获得所有权并授予其所有权限后，我也无法打开目录：

sudo mkdir /path/to/the/directory/
sudo chown -R username:username /path/to/the/directory/
sudo chmod -R 777 /path/to/the/directory/

我得到：

$sudo ls -al /path/to/the/directory/
total 0
drwxrwxrwx 1 username username   0 nov 16 15:13 .
drwx------ 1 root     root     208 nov 16 15:13 ..
$ ls -al /path/to/the/directory/
ls: cannot access '/path/to/the/directory/': Permission denied

会发生什么？

在系统设置 > 蓝牙中，搜索设备时可以看到 Bose QC 35 但配对失败。

在多次尝试并使用PIN 选项播放后，我设法配对它，但一旦在System Settings > Sound中选择它，它就会失败并回退到内置音频或播放一些乱码。
