Wrong password every time after changing login password

[leopoldog]

After changing password with "passwd" command it's not possible to open the keyring anymore.
Each time I have the dialog that open asking me for the password.
I've tried to enter the old password and the new password but nothing changes.
I've changed back the login password to the old one but even in that case the seahorse password dialog opens saying that the login password doesn't matches the keyring password and asking me to enter it again.

I need a procedure to change the keyring password without login into the seahorse, so that it can match the login password of Ubuntu.

Thank you for your bug report, when using passwd to change your password the pam stack should update the keyring one as well, unsure why that's not working for you. Could you add your 'journalctl -b 0' log after a password change?

All the time I receive this error in the journal.

I've receiving the same error when I try to change from the old password to the new and vice versa.
I was expecting to have no error if the change was from the old password to the new and an error in the other way.

Maybe is because the first time I've changed the password I was logged in with root, but this should not be a problem if the wallet change is made via PAM.

My problem is not that the wallet doesn't change password automatically (even if it's practical) but that I can't change the wallet password anymore because even the old password is considered wrong.

Status changed to 'Confirmed' because the bug affects multiple users.
