after which Dropbox installed without complaint. With any luck, that apt-mark auto will mean that once Dropbox does get its act together and stops depending on packages deprecated seven years ago, apt will clean up all by itself and let me forget I even had to do this .
Indeed the Dropbox team should update the dependencies for the deb packages. For completeness I did attatch two links to debian bug report tool as well as to Mojang (Minecraft) Bug report. One of the debian package maintainers explained the current situation very detailed
Dropbox seems to work just fine with the quick and dirty transitional package I built with equivs, so it doesn't seem like it actually does depend on any of the libraries formerly bundled in the long-deprecated libpango1.0-0 package other than libpango-1.0-0 itself. That *should* make the change required inside Dropbox's own deb package completely trivial; just adding the - to the dependency should be all that needs to be done.
