Dropbox doesn't quite work right under KDE because it relies on nautilus. There's a package called kdropbox available that's supposed to make Dropbox easier to use. I installed it, but calling kdropbox doesn't find anything. The package is about ten years old and doesn't seem to be maintained. Does anyone here know anything about it?
To use Dropbox with Dolphin file manager you have to install two packages - Dropbox and Dolphin plugins by
then run Dropbox for first time using its icon or
dropbox start -i
command. Provide your Dropbox credentials in the web-browser, wait it to run first sync.Then open Dolphin, go to Settings → Configure Dolphin (or Ctrl+Shift+,), visit Services (or Context Menu) tab to enable Dropbox plugin, press OK to confirm the new settings. Restart Dolphin and enjoy:
