No further info available. This is the first occurrence of the error. The system updater was working that time.

This happens in the pam-auth-update call, reassigning to PAM.

The errors in the log are:

Use of uninitialized value $reply in scalar chomp at /usr/share/perl5/Debconf/FrontEnd/Passthrough.pm line 66.
Use of uninitialized value $reply in concatenation (.) or string at /usr/share/perl5/Debconf/FrontEnd/Passthrough.pm line 67.
Use of uninitialized value $reply in split at /usr/share/perl5/Debconf/FrontEnd/Passthrough.pm line 68.

This looks like a problem with debconf, not with pam. Please show the output of the commands 'debconf-show debconf' and 'debconf-show libpam-runtime'.

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