Hi The package name of libqwtplot3d-qt3 and libqwtplot3d-qt4 have been changed to libqwtplot3d-qt3-0 and libqwtplot3d-qt4-0 respectively. This requires rebuilding of the following packages: gnuradio_3.2.2.dfsg-1 . ALL . -m "Rebuild against renamed libqwtplot3d-qt4-0" labplot_1.6.0.2-3 . ALL . -m "Rebuild against renamed libqwtplot3d-qt3-0" Thanks Gudjon
