It turns out that all you need to do is simply add a dependency on libhdf5-100 and then the package is perfectly installable!
(Otherwise I don't understand the point of uploading a package that nobody can install using apt.) Here is what I successfully installed: Package: qgis Version: 3.4.8+dfsg-1 -- System Information: Debian Release: 10.0 APT prefers experimental APT policy: (990, 'experimental'), (500, 'unstable') Architecture: amd64 (x86_64) Versions of packages qgis depends on: ii libc6 2.28-10 ii libexpat1 2.2.6-1 ii libgcc1 1:9.1.0-2 ii libgdal20 [gdal-abi-2-4-0] 2.4.1+dfsg-1~exp1 ii libgeos-c1v5 3.7.1-1 ii libgsl23 2.5+dfsg-6 ii libgslcblas0 2.5+dfsg-6 ii libpq5 11.3-1 ii libproj13 5.2.0-1 ii libqca-qt5-2 2.1.3-2 ii libqgis-3d3.4.8 3.4.8+dfsg-1 ii libqgis-analysis3.4.8 3.4.8+dfsg-1 ii libqgis-app3.4.8 3.4.8+dfsg-1 ii libqgis-core3.4.8 3.4.8+dfsg-1 ii libqgis-gui3.4.8 3.4.8+dfsg-1 ii libqgis-native3.4.8 3.4.8+dfsg-1 ii libqscintilla2-qt5-13 2.10.4+dfsg-2 ii libqt53dcore5 5.11.3+dfsg-2 ii libqt53dextras5 5.11.3+dfsg-2 ii libqt53dinput5 5.11.3+dfsg-2 ii libqt53dlogic5 5.11.3+dfsg-2 ii libqt53drender5 5.11.3+dfsg-2 ii libqt5concurrent5 5.11.3+dfsg1-1 ii libqt5core5a 5.11.3+dfsg1-1 ii libqt5dbus5 5.11.3+dfsg1-1 ii libqt5gui5 5.11.3+dfsg1-1 ii libqt5keychain1 0.9.1-2 ii libqt5network5 5.11.3+dfsg1-1 ii libqt5positioning5 5.11.3+dfsg-2 ii libqt5printsupport5 5.11.3+dfsg1-1 ii libqt5qml5 5.11.3-4 ii libqt5quick5 5.11.3-4 ii libqt5quickwidgets5 5.11.3-4 ii libqt5serialport5 5.11.3-2 ii libqt5sql5 5.11.3+dfsg1-1 ii libqt5svg5 5.11.3-2 ii libqt5webkit5 5.212.0~alpha2-21 ii libqt5widgets5 5.11.3+dfsg1-1 ii libqt5xml5 5.11.3+dfsg1-1 ii libqwt-qt5-6 6.1.4-1 ii libspatialindex5 1.9.0-1 ii libspatialite7 5.0.0~beta0-1~exp2 ii libsqlite3-0 3.27.2-2 ii libstdc++6 9.1.0-2 ii libzip4 1.5.1-4 ii ocl-icd-libopencl1 [libopencl1] 2.2.12-2 ii python3-qgis 3.4.8+dfsg-1 ii qgis-common 3.4.8+dfsg-1 ii qgis-providers 3.4.8+dfsg-1 Versions of packages qgis recommends: pn qgis-plugin-grass <none> Versions of packages qgis suggests: pn gpsbabel <none> -- no debconf information The only warnings I saw were Setting up qgis-providers (3.4.8+dfsg-1) ...
