[Pkg-samba-maint] Bug#833164: samba-vfs-modules 2:4.4.5+dfsg-2 breaks samba-libs 2:4.2.10+dfsg-0+deb8u3

[Willem Mulder]

Package: samba-vfs-modules
Version: 2:4.4.5+dfsg-2
Severity: minor

Dear Maintainer,

While upgrading from jessie to stretch, dpkg failed to install
samba-vfs-modules 2:4.4.5+dfsg-2 due to a file conflict with samba-libs
2:4.2.10+dfsg-0+deb8u3:

Unpacking samba-vfs-modules (2:4.4.5+dfsg-2) over
(2:4.2.10+dfsg-0+deb8u3) ...
dpkg: error processing archive
/var/cache/apt/archives/samba-vfs-modules_2%3a4.4.5+dfsg-2_amd64.deb
(--unpack):
 trying to overwrite
'/usr/lib/x86_64-linux-gnu/samba/libnon-posix-acls.so.0', which is also
in package samba-libs:amd64 2:4.2.10+dfsg-0+deb8u3
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

This was also noted in bug #832880, but this is a different problem than
described there. Steps to reproduce:

* Install jessie base system and samba-libs
* Install samba-vfs-modules from stretch (without upgrading samba-libs)

Installing samba-vfs-modules via apt on this base system upgrades
samba-libs before installing samba-vfs-modules, but the order does not
seem to be guaranteed as I noticed while upgrading my own system.

Kind regards,

Willem Mulder
