Comment 23 for bug 283477

Same issue here. KDE's screen lock had crashed, so I dropped to the command line. I fat fingered my password into the user field after getting it wrong initially, so the first thing I did once I got a shell was to change my password.

I then rebooted, upon which I got:

Jul 31 08:02:01 void ecryptfs-insert-wrapped-passphrase-into-keyring: Incorrect wrapping key for file [/home/reuben/.ecryptfs/wrapped-passphrase]
Jul 31 08:02:01 void ecryptfs-insert-wrapped-passphrase-into-keyring: Error attempting to unwrap passphrase from file [/home/reuben/.ecryptfs/wrapped-passphrase]; rc = [-5]
Jul 31 08:05:01 void CRON[4528]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1)
Jul 31 08:05:04 void sudo: pam_ecryptfs: Passphrase file wrapped

Jul 31 08:05:04 void sudo: pam_ecryptfs: Error adding passphrase key token to user session keyring; rc = [-5]

I then changed my password back to what it was, rebooted, and this time it was able to wrap the key.
