Here's the problem:

# ecryptfs-migrate-home -u <user>
INFO:  Checking disk space, this may take a few moments.  Please be patient.
INFO:  Checking for open files in /home/<user>
Enter your login passphrase [<user>]: 

************************************************************************
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.
************************************************************************

Done configuring.

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

This was done over an SSH session.

Can't be done over SSH. From experience, has to be done from a terminal (i.e. Alt+F1) as suid root.

It is possible to do this over ssh, but directly. If you login as a root it works. If you try over sudo su - problem persists.

  • Did you mean: It is possible to encrypt your user home over ssh, but only if you do this directly with root. If you try over `sudo su -` the problem will persist. – John K. N. Nov 10 '16 at 11:52
