That seems to have fixed it. I changed that entry in /etc/pam.d/common- password like this:
#password [success=1 default=ignore] pam_unix.so obscure sha512 password required pam_unix.so obscure sha512 And now it throws out a better error message for both root and regular users when they fail changing their passwords: ROOT: [EMAIL PROTECTED]:/etc/pam.d# passwd Enter new UNIX password: Retype new UNIX password: Sorry, passwords do not match passwd: Authentication information cannot be recovered passwd: password unchanged [EMAIL PROTECTED]:/etc/pam.d# USERX: [EMAIL PROTECTED]:/$ passwd Changing password for userX. (current) UNIX password: Enter new UNIX password: Retype new UNIX password: Sorry, passwords do not match passwd: Authentication information cannot be recovered passwd: password unchanged [EMAIL PROTECTED]:/$ -- passwd - passwords do not match but updated successfully https://bugs.launchpad.net/bugs/272232 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
