I'm using both Ubuntu and Windows, I'm having problems with signing into Google Chrome to sync my user data across different computers and my mobile phone (I've stopped using my phone a while ago). And oddly enough I'm also having problems accessing some Google sites, Google+ and Google Groups among others.
chrome://sync shows the following error,
Unrecoverable error detected at chrome/browser/sync/profile_sync_service.cc OnSyncConfigureRetry : Configure failed to download.
How can I fix this?
