Why do I get this fabric put error?

Question

So I am trying to move a specific file from my computer onto the remote server. However, when I try to use fab to do this it returns the following error:

Fatal error: put() encountered an exception while uploading '/home/jonathan/Dropbox/facebook-crawler/worker_scraper.py'
Underlying exception:  
    size mismatch in put!  0 != 7304

Fab function:

@roles('workers')
def move_scraper():
    put('~/Dropbox/facebook-crawler/worker_scraper.py', '~/facebook-crawler/')

anyone have any idea why this is happening?

Answer 1

Just thought I should add an official answer. I ran into this error on a Raspberry Pi (had never seen it through quite a bit of experience with Fabric).

I was out of disk space
