[Bug 1629038] Re: 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

[ChristianEhrhardt]

Gary (and Franco) - back when debugging this case it was due to multiple
mixed libs and binaries installed that didn't work together. After the
debugging the solution was to re-clean the system related to those
binaries/libraries - but it stays an uncommon case caused by some
special local setup/config - at least that was the theory.

So I'm interested if you are really hitting "the same" meaning like:
samba: /usr/lib/x86_64-linux-gnu/samba/libtime-basic.so.0: version `SAMBA_4.3.9_UBUNTU' not found (required by /usr/lib/i386-linux-gnu/libsamba-util.so.0)

Or just some other sort of "failed to install/upgrade: subprocess
installed post-installation script returned error exit status 1" as
there can be many others.

If you hit really the same, please:
1. add your insight on your systm setup related to sambe where the stale binaries/so's could come from in your case
2. try the workarounds to clean as described above and report if they helped in your case

If you are hitting a different issue on upgrade please report a new bug
