Steve, I ran into the same issue just yesterday. sudo started segfaulting right after installing a few samba-related packages. I've been able to make a backtrace (see attachment).
Commenting out the line with pam_smbpass.so in /etc/pam.d/common-auth has fixed the problem for me. ** Attachment added: "gdb-sudo.txt" http://launchpadlibrarian.net/21483792/gdb-sudo.txt -- silent login/gdm failures and sudo segfaults with smbpasswd enabled https://bugs.launchpad.net/bugs/292791 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
