Ok, I got it solved. Here's the answer for posterity.
I think something left over from a previous install was messing up the communication between dropbox and chrome. I changed my default browser to firefox, removed and reinstalled dropbox, and this time it worked just fine.
Hey @richardjconrad,
No problem with the firewall, turns out it's not enabled by default in ubuntu. And I don't have any proxies set up. Seems to me like the problem has to do with Dropbox's ability to communicate with the browser - it can open one but it doesn't go to the right page.
I also just ran into this issue. When I tried to sign in to dropbox, it would simply open an empty chrome window.
Finally, I set the default browser to Firefox and the Dropbox sign in worked correctly, bringing up a firefox sign in window.
Can you fix the Ubuntu (Debian) version of Dropbox so that it works correct when Chrome is the default browser?
Hey @ginobean,
We can definitely send that over to our team specialists as a feature request, thanks for getting in touch here with this feedback!
Defentely a bug in Dropbox setup. If it needs to use FF then it needs to work nicely if Chrome is default browser.
Thx
Does not seem like a fix.
I tried using Firefox as default browser. It is not working.
Ginobean's answer works for me. Just setting Firefox as the default browser so that the sign-in redirect goes to the correct page. I did not uninstall and re-install Dropbox. Ubuntu 14.04 here, Dropbox installed using .deb file via GUI.
