Not mount the encrypted home partition after updated - Ubuntu

Environment
  • Ubuntu 12.04

Content
Each time kernel updated, it does not mount the encrypted home partition.

In console mode, it shows
Could not chdir to home directory /home/User: No such file or directory
To run a command as administrator (user "root"), use "sudo ".
See "man sudo_root" for details.

It is because of Pluggable Authentication modules (PAM) not enable - "Mount volumes for user". To enable it back, it can be going to recovery mode, to root mode, then
#mount -o remount,rw /

#pam-auth-update
