I decided to figure out how to recover data on a disk if the system does not start. It's better to do it before it happens;)

Since there is no definitive correct answer for Linux Mint 18.3 KDE anywhere, I had to find a solution myself.

Good topic for other OS like "Ubuntu": https://askubuntu.com/questions/238047/how-do-i-mount-an-encrypted-home-directory-on-another-ubuntu-machine

  1. Boot PC from Live CD (Linux mint 18.3 KDE)
  2. Run in console: sudo ecryptfs-manager and exit (select 4 => Enter) (see bug 455709 mount: mount(2) failed: No such file or directory)

sudo ecryptfs-manager result

  1. Find your encrypted /home/UserName directory by checking every device in Dolphin. In my case, it is located on a separate volume (But in your case, most likely this path will be inside the home folder like: /media/mint/1234567-1233-1233-32423-1a95b2c5dc68/home/UserName)

encrypted home directory in separated volume

  1. Open dolphin in home directory "as root"

Open dolphin in home directory

  1. Press Alt + . for show hidden files

  1. Go to .ecryptfs folder inside and try to find .Private folder (in every new Folder you have to "Show hidden files" by pressing Alt + . !!!)

  2. As final your .Private folder:

  1. Press F4 for opening console here
  2. Run in console: ecryptfs-recover-private ./.Private (Passphrase is your login PC Password !!! )

enter image description here

  1. Well done! Go to /tmp/ecryptfs.JSiaYsbz directory using cd

enter image description here

p.s. Use the flag --rw (in step 9) to mount the encrypted filesystem as read and write (read only as default!)
