Hi, so the lib that is missing the other symbols "should" not be installed at all.
I also found that I had only x86_64 versions of it. $ ll /usr/lib/*/libndr.so.0 lrwxrwxrwx 1 root root 15 Sep 23 19:44 /usr/lib/x86_64-linux-gnu/libndr.so.0 -> libndr.so.0.0.5 $ dpkg -S /usr/lib/*/libndr.so.0 samba-libs:amd64: /usr/lib/x86_64-linux-gnu/libndr.so.0 On i386 the same looks like this: $ ll /usr/lib/*/libndr.so.0 lrwxrwxrwx 1 root root 15 Sep 23 19:45 /usr/lib/i386-linux-gnu/libndr.so.0 -> libndr.so.0.0.5 $ dpkg -S /usr/lib/*/libndr.so.0 samba-libs:i386: /usr/lib/i386-linux-gnu/libndr.so.0 Both working fine. I tried to force some chaos by installing i386 packages onto x86_64 system and vice versa. dpkg --add-architecture i386 apt-get update # for dependencies I need to install more than just libs apt-get install samba-libs:i386 python-talloc:i386 python:i386 # apt is smart about conflicts as I see [...] The following packages will be REMOVED: python python-crypto python-ldb python-minimal python-samba python-talloc python-tdb python2.7 python2.7-minimal samba samba-common-bin samba-dsdb-modules samba-libs samba-vfs-modules [...] # And afterwards I get a correct working samba: $ ll /usr/lib/*/libndr.so.0 lrwxrwxrwx 1 root root 15 Sep 23 19:45 /usr/lib/i386-linux-gnu/libndr.so.0 -> libndr.so.0.0.5 $ dpkg -S /usr/lib/*/libndr.so.0 samba-libs:i386: /usr/lib/i386-linux-gnu/libndr.so.0 You seem to have a mixed environment, for that a few questions. - do you have a 64 or 32 bit setup in general? - and old experiments around samba libs? - any experiments around multiarch? - Did you maybe in the past build a custom 32bit samba that still has libs around interfering with the packaged samba? - please report "ll /usr/lib/*/libndr.so.0" and "dpkg -S /usr/lib/*/libndr.so.0" - if your /usr/lib/i386-linux-gnu/libndr.so.0 doesn't belong to a package where did it come from? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629038 Title: package samba 2:4.3.11+dfsg-0ubuntu0.16.04.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1629038/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
