Ubuntu 12.04
37MB out of 2GB has been uploaded in the past 7 hours. And that happened in the first few minutes. Then nothing. This is a test to see if it works and then pay for more space. Why pay for something that does not work?
Dropbox has always worked and never failed.
I Googled this problem and the web forums are full of complaints like this.
u1sdtool -s tells me all is OK. But clearly it's not.

If anyone has any insight into this I'd appreciate it. Otherwise I'm removing Ubuntu One and staying with Dropbox.
