It seems to be a problem with a changed Syntax in the /etc/pam.d/common-* files. The problem occurs when upgrading the system while having a manually changed config in the /etc/pam.d/common-* files, which is quite common when using LDAP auth.
To solve the problem try to run: "pam-auth-update --force" This rebuilds the common-* files from scratch, so have a look at them afterwards. -- su does not work from shell https://bugs.launchpad.net/bugs/482131 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
