In Windows/Mac, you just have to download the respective software and uninstall it in your system (Be sure to uninstall the older version first). In Ubuntu, if you have installed Dropbox via PPA or deb file, you will find that it your Dropbox does not get updated with the system upgrade. 1. To upgrade your Dropbox account to 1.0, first shutdown the current Dropbox service. You should be able to do it by clicking the Dropbox icon at the panel and select “Quit Dropbox”. 2. Next, open your Nautilus File Manager and go to the Home folder. Press “Ctrl +h” to display hidden files. Scroll down the list until you see the .dropbox-dist. Rename the folder as .dropbox-dist-backup. 3. Lastly, go to “Applications -> Internet -> Dropbox“. It will now prompt you to install the proprietary daemon. Click Ok to proceed. Once the download is completed, you will be running version 1.0 of Dropbox.
To configure the selective sync, click on the Dropbox icon at the top panel and select “Preferences”. Go to the “Advanced” tab. You should see the “Selective Sync” button. Click on it and you will be able to choose the folders to sync.
