Right there is the problem. libharfbuzz0a breaks/replaces (and rightfully does
so) libharfbuzz0. That should be fine, aptitude should resolve to uninstall
libharfbuzz0. Do you have something installed that depends on libharfbuzz0 other
than pango? What happens if you say No to aptitude's proposed solution? Does it
offer another option that is satisfiable (i.e. that will remove libharfbuzz0 but
not half of your system). Keep saying No until aptitude finds the right solution.
