Bug#863885: libterralib: superfluous Conflicts/Replaces on libterralib3 cause problems on upgrades to stretch

[Andreas Beckmann]

Package: libterralib
Version: 4.3.0+dfsg.1-2
Severity: serious
Tags: jessie

Hi,

during a test with piuparts I noticed upgrade problems from jessie to
stretch that can be attributed to libterralib in jessie.

libterralib/jessie has (unversioned) Conflicts/Replaces: libterralib3,
but there has never been such a package before stretch ...
This can cause upgrade problems, since apt will not consider the new
libterralib3 package as a valid installation candidate (and will try to
keep the old libterralib installed instead).

This bug is very hard to work around in stretch. Please fix it in jessie
by removing the superfluous C+R.

See #859986 for a similar problem in openmpi.
