[Bug 1718658] Re: ecryptfs-mount-private fails to initialize ecryptfs keys

[Xavier Guillot]

I don't agree with the last comme,nt : I have a fresh install of 18.04
and get the same error when trying to recover my old savec Private
directory :

Enter your MOUNT passphrase: 
mount: /tmp/ecryptfs.fSC9TkTG : échec de l’appel système mount(2) : Aucun fichier ou dossier de ce type.
ERROR: Failed to mount private data at [/tmp/ecryptfs.fSC9TkTG].

Title:
  ecryptfs-mount-private fails to initialize ecryptfs keys

Status in ecryptfs-utils package in Ubuntu:
  Confirmed
Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  ecryptfs-mount-private fails to mount the ecryptfs after the 1st
  reboot after creating the ecryptfs by ecryptfs-setup-private.

  After the unsucessful attempt dmesg contains:

  [ 1265.695388] Could not find key with description: [<correct key ID>]
  [ 1265.695393] process_request_key_err: No key
  [ 1265.695394] Could not find valid key in user session keyring for sig specified in mount option: [<correct key ID>]
  [ 1265.695395] One or more global auth toks could not properly register; rc = [-2]
  [ 1265.695396] Error parsing options; rc = [-2]

  Note: The correct key ID has been replaced in the "<correct key ID>".

  I also accidentally found an workaround - just running ecrytpfs-
  manager and then the ecryptfs-mount-private (it does not ask for
  password for the second time and mounts the ecryptfs correctly):

  host:~$ ecryptfs-manager

  eCryptfs key management menu
  -------------------------------
  	1. Add passphrase key to keyring
  	2. Add public key to keyring
  	3. Generate new public/private keypair
  	4. Exit

  Make selection: 4
  host:~$ ls Private/
  Access-Your-Private-Data.desktop  README.txt
  host:~$ ecryptfs-mount-private 
  host:~$ ls Private/
  <ecryptfs content is present>
