I have had the same problem. Samba was installed a fews days ago. Today i've installed Crossover Games, which i deinstalled a few minutes later. Later i would start synaptic but it doesn't worked. Every time i wanted to open a program using sudo or gksudo/gksu i got only one message: "Segmentation fault". Nothing else.
dpkg --purge libpam-smbpass worked for me. -- Purging samba breaks login (pam_smbpass.so segfaults) https://bugs.launchpad.net/bugs/260687 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
