Bug#825836: qgis: Stronger dependency between packages

[Nelson A. de Oliveira]

Source: qgis
Severity: wishlist

While downgrading qgis to 2.14.3+dfsg-1 (to avoid #825091 and test
#824624) I stayed with this (only greped for 'gqis', but should apply to
the other dependencies as well):

=====
libqgis-analysis2.14.3             2.14.3+dfsg-2
libqgis-app2.14.3                  2.14.3+dfsg-2
libqgis-core2.14.3                 2.14.3+dfsg-2
libqgis-customwidgets              2.14.3+dfsg-2
libqgis-gui2.14.3                  2.14.3+dfsg-2
libqgis-networkanalysis2.14.3      2.14.3+dfsg-2
libqgis-server2.14.3               2.14.3+dfsg-2
libqgisgrass7-2.14.3               2.14.3+dfsg-2
libqgispython2.14.3                2.14.3+dfsg-2
python-qgis                        2.14.3+dfsg-1
python-qgis-common                 2.14.3+dfsg-1
qgis                               2.14.3+dfsg-1
qgis-common                        2.14.3+dfsg-1
qgis-dbg                           2.14.3+dfsg-2
qgis-providers                     2.14.3+dfsg-1
qgis-providers-common              2.14.3+dfsg-1
=====

Dependencies are fully satisfied but I still hit #825091 (most probably
caused by the mixed package versions).

Shouldn't we have stronger dependencies here?
For example, instead qgis depending on libqgis-core2.14.3 (>= 2.14.3), I
guess it should depends exactly on libqgis-core2.14.3 (= 2.14.3+dfsg-1).

Thank you!

Best regards,
Nelson
