-- ecryptfs private wrapped passphrase with wrong password during password change https://bugs.launchpad.net/bugs/305882 You received this bug notification because you are a member of eCryptfs, which is subscribed to ecryptfs-utils in ubuntu. Status in “ecryptfs-utils” source package in Ubuntu: Incomplete Status in “pam” source package in Ubuntu: New Bug description: Binary package hint: ecryptfs-utils To reproduce: 1. On command line, attempt to change your password to a weak password (like "yes"). 2. Actually change your password to a strong password. I found that ecryptfs wrapped the passphrase in the weak password instead of the final password I chose.
