I spent some time this morning trying to designate an ext4 partition as my Dropbox sync location, but Dropbox kept rejecting my ext4 partition. This related question: Dropbox: ext4 isn't ext4 offered some suggestions but at some point the Dropbox icon disappeared from my system tray.
Dropbox is running -- I created a new text file and it syncs to another Dropbox instance promptly, but without the tray icon I can't open the preferences and if I cant open the preferences I can't designate a new sync location.
There are a lot of questions that seem related, but no so far none of the solutions work.
As suggested in several answers, I ran dropbox stop && DBUS_SESSION_BUS_ADDRESS="" dropbox start
which doesn't seem to have made a difference -- still no system tray icon. It did return two warnings which seem relevant:
(dropbox:3946): libappindicator-WARNING **: 19:05:47.t941: Unable to get the session bus: The given address is empty
(dropbox:3946): LIBDBUSMENU-GLIB-WARNING **: 19:05:47.941: Unable to get session bus: The given address is empty
What can I do with this libappindicator-WARNING
? Or is there a way to pull up the Dropbox preferences window without the system tray icon? I'm on 18.04, running Gnome. dropbox status
reports that Dropbox is up to date.
