我需要恢复我的系统...更新失败后它崩溃了。我试图用谷歌搜索解决方案，但我得到了这个：
[manjaro-deepin manjaro]# mkdir /mnt
mkdir: cannot create directory ‘/mnt’: File exists
[manjaro-deepin manjaro]# lsblk

mount: /mnt: unknown filesystem type 'swap'.
[manjaro-deepin manjaro]# 'swap'
bash: swap: command not found
[manjaro-deepin manjaro]# sudo mount /sda /mnt
mount: /mnt: special device /sda does not exist.
[manjaro-deepin manjaro]# mount /dev/sda1 /mnt
mount: /mnt: unknown filesystem type 'swap'.
[manjaro-deepin manjaro]#
我究竟做错了什么？
