Ubuntu – Keeping the time stamp when syncing with Ubuntu One

The easiest way to add all your own music is just to mark the folder it's in as being synced with Ubuntu One.

See Ubuntu One : Help : FAQs - How do I move my existing music to Ubuntu One? for details.

Basically, just right-click on your Music folder (or wherever your music is stored) and pick Ubuntu One > Synchronize this folder from the context menu. This will copy your music into your personal cloud, and then it's all available for streaming.

I'm not a big fan or user of Ubuntu One, but I'll try to help. You'll probably need to outline some additional details :

1. Version of Ubuntu you're running.
2. Size of folder you're trying to sync.
3. How are you connected to the internet? Is this is a home broadband service, or a corporate setting?
4. Are you using a proxy server to connect to the internet?
5. Are you using a firewall, hardware or otherwise? Perhaps one built in to your broadband router (what make is your broadband router)?
6. Please post the results of running sudo ufw status in a terminal.

You might also benefit from running the (unofficial, I think) gnome-panel indicator applet for Ubuntu One. Run this to install it :

sudo add-apt-repository ppa:rye/ubuntuone-extras
sudo apt-get update && sudo apt-get install ubuntuone-indicator

Then run it with ALT-F2 and ubuntuone-indicator. I think it's in System/Preferences too. This applet gives you quick access to see what the last file synced was and what Ubuntu One's current status is.

And it sounds like you've already done this, but best check the official FAQ here : https://wiki.ubuntu.com/UbuntuOne/FAQ#Files

Finally, if you followed Jorge's link to the Ubuntu One blog, you'll see that there's an official support program in place. Raise a ticket here : https://one.ubuntu.com/support/contact/
