************************************************************************
YOU SHOULD RECORD YOUR MOUNT PASSPHRASE AND STORE IT IN A SAFE LOCATION.
ecryptfs-unwrap-passphrase ~/.ecryptfs/wrapped-passphrase
THIS WILL BE REQUIRED IF YOU NEED TO RECOVER YOUR DATA AT A LATER TIME.

chown: cannot access ‘/dev/shm/.ecryptfs-<user>’: No such file or directory
mount: mount(2) failed: No such file or directory
ERROR: Could not mount
这是通过 SSH 会话完成的。
答案1
无法通过 SSH 完成。根据经验，必须从终端（即 Alt+F1）以 suid root 身份完成。
答案2
可以通过 ssh 执行此操作，但可以直接执行。如果您以 root 身份登录，则可行。如果您尝试通过 sudo su - 问题仍然存在。
