求助：加密磁盘挂载失败

笔记本升级了16.04后，经常出现屏保死机和开机无法挂载磁盘问题。
在Sys log里面出现下面信息

这个怎么解决？

说个懒人办法，把fstab里面的uuid换成对应的设备，比方说/dev/sda1这样的，至于屏保死机……那就不用屏保…… :Noting

fstab content

# /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/ubuntu--vg-root / ext4 errors=remount-ro 0 1
# /boot was on /dev/sda1 during installation
UUID=f2f988f6-6ce0-4e98-b9bb-88a7dfaca216 /boot ext2 defaults 0 2
/dev/mapper/ubuntu--vg-swap_1 none swap sw 0 0
系统日志里面的那个uuid设备并不在fstab里面啊

lvm……略麻烦啊，你直接终端敲mount，看看输出有啥

是新手嗎

安裝時你可能選擇 lvm 了 (見下圖第四項)
新手不建議一開始就入門 lvm

安裝時選擇最下面 something else (見下圖最後一項)
比較適合新手入門

新手推薦先使用 Ubuntu Live USB 登入試用桌面
使用 gparted 依計畫分割好硬盤
然後安裝時選擇最後一項 something else
依計畫掛載
安裝比較順利
