Re: Unable to sync some folders while others sync without problem
From what I've seen, the Ubuntu One support team doesn't appear to be a very fast responder. It might be worth your while reporting a bug on Launchpad as well. I've had a response (though not immediate) when I've done that.
A workaround might be to define new folders from scratch and move your Google drive documents to those. Then you can delete the Google drive folder (since it will have nothing useful in it). You can mark these new folders as ones that need syncing.
If you do that, in my experience you don't need to upload everything again. The server somehow knows that the files just need to be moved.
Please, people, remember to BACKUP before you install that new system. Same if you're upgrading.
