Comment 9 for bug 584852

@sebastien, your problem is not related to this bug report. In your case it was not possible for your system to locate the server that synchronization daemon should connect to. Please check your DNS settings and open a new bug in case
$ host fs-1.one.ubuntu.com
Produces something like "fs-1.one.ubuntu.com has address 174.129.241.144" but syncdaemon still produces the exception you pasted.

@sabrina, could you please try running syncdaemon in debug mode:
1. Shut down ubuntuone-syncdaemon using
  $ u1sdtool --quit
2. Run ubuntuone-syncdaemon from the commandline directly -
  $ /usr/lib/ubuntuone-client/ubuntuone-syncdaemon --debug > debug.log
3. Signal syncdaemon to connect
  $ u1sdtool --connect
4. Once you get an error "Not enough space for upload" in debug.log please attach debug.log file to this bug report.
