Hi David-
So I'll record the rest of our conversation here, and convert this "bug"
into a "question".
The tools you actually need are:
* ecryptfs-rewrap-passphrase
* ecryptfs-insert-wrapped-passphrase-into-keyring
After moving your passphrase from the first machine to the second, you should
manually rewrap the passphrase on the second machine. You will need your "old"
login passphrase from the first machine, and your "new" login passphrase from
the second machine:
$ ecryptfs-rewrap-passphrase $HOME/.ecryptfs/wrapped-passphrase
Then, you'll want to run:
$ ecryptfs-insert-wrapped-passphrase-into-keyring
$HOME/.ecryptfs/wrapped-passphrase
This will get your mount passphrase into the keyring. At this point, you
should be able to run:
$ ecryptfs-mount-private

Bug description:
STEPS TO REPRODUCE:
1) You need to have an installation of Ubuntu 9.04 and 8.10 with the same
username but different login passphrases. When you set up your private
directory on 9.04 be sure to use a different mount passphrase then your login
passphrase.
2) Migrate /home directory from a computer running 9.04 Alpha 3 to a computer
running 8.10
3) Install ecryptfs-utils
4) run ecryptfs-mount-private
5) error is produced:
Error attempting to unwrap passphrase and insert into the user session keyring;
rc = [-5]. Check the system log for more information from libecryptfs.
WORKAROUND:
By editing the ecryptfs-mount-private script slightly, and executing it, it
asks for the login passphrase (for the first 9.04 computer) and mounts the
~/Private directory. I attached a diff between the edited version and the
original version.
TERMINAL OUTPUT:
kompu...@ubuntu:~$ ecryptfs-mount-private
Enter your login passphrase:
Unable to read salt value from user's .ecryptfsrc file; using default

Dustin, there is no need to make a change, this is simply here as a record of
the issue and the discussion we had.
