Thank you for taking the time to report this bug and helping to make Ubuntu better.
It looks like a local installation of PostgreSQL is impacting the correct operation of winbindd - as you can see in the error report its trying to use libraries in /opt/PostgreSQL/psqlODBC/lib/ which are not the Ubuntu supplied versions of these libraries (which would reside in /usr/lib). Have you enabled this additional location by adding a configuration file into /etc/ld.conf.d? It looks like your local PostgreSQL installation and winbindd might not co-exist that well on the same server. Please could you provide the following commands output as an attachment to this bug: ldconfig -p Thanks ** Changed in: samba (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/735296 Title: package winbind 2:3.4.7~dfsg-1ubuntu3.4 failed to install/upgrade: underproces installed post-installation script returnerede afslutningsstatus 127 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
