Hi, Problem lies not in qgis, but in the fact that other packages that depends on libgsl* have not yet been updated.
If you can do without inkscape for a while, you can force installation this way: # LANG=C apt install qgis libgsl2 The following packages will be REMOVED: enblend enfuse hugin indi-bin inkscape kdeedu libgsl0ldbl libindialignmentdriver1 step The following NEW packages will be installed: libgsl2 The following packages will be upgraded: python-qgis python-qgis-common qgis qgis-common qgis-plugin-globe qgis-plugin-globe-common qgis-providers qgis-providers-common If you need both qgis & inkscape asap, you can dig snapshots.debian.org and down load 7 needed packages manually then install those with "dpkg -i " Greets, Alexandre Detiste
