If you try to install the official Dropbox RPM package, it will fail to install on Fedora 37 with an error like this:
Problem: conflicting requests - nothing provides libnautilus-extension.so.1()(64bit) needed by nautilus-dropbox-2020.03.04-1.fc21.x86_64
In other words, you can’t use the official Dropbox installer on Fedora 37.
Nautilus changed extension API in GNOME 43, but Dropbox haven’t updated their extension yet. There is a fix provided by the community, but Dropbox maintainers haven’t responded yet.
RPMFusion, a popular alternative place to get Dropbox, removed the Dropbox package for similar reasons - not able to build it and also lacking maintainers.
