Bug#677403: libgdal1: Please add Breaks: libgdal1-1.6.0

[Andreas Beckmann]

Package: libgdal1
Version: 1.9.0-3
Severity: important

Usertags: piuparts


Hi,

while doing piuparts tests I noticed a strange upgrade failure in the
qgis-plugin-grass package because apt-get decided to remove this package
instead of some obsolete libraries. Log is attached.
The test was a dist-upgrade from squeeze to wheezy.

The hdf5 and gdal library transitions are not trivial for apt ...
I rebuilt the gdal package with an added
  Breaks: libgdal1-1.6.0
in libgdal1 and thereafter the distupgrade went smooth, this little
added conflict has has turned the favor to removing a bunch of obsolete
libs in order to allow some new ones to be installed.

Part of the apt-get dist-upgrade problemresolver debugging output:

for 1.9.0-2:
