UbuntuOne sync applet reported it's too fresh for server-side to support it. 1st time ever used account and sync.

Binary package hint: ubuntuone-client

Added a file via web upload manually before.
Have just added this machine to my account and then u1 applet informed me of "Capabilities mismatch with server".

Janus,
Thank you for your bug report and helping to make Ubuntu better. The capabilities mismatch is fixed a lot of times by updating your client. You can do that by opening a Terminal (Applications > Accesories > Terminal) and running the following command.

sudo add-apt-repository ppa:ubuntuone/stable && sudo apt-get update && sudo apt-get upgrade

Let us know how that goes.

Thank you,

Attempted to update all at once (from 9.10 official out of CD and up to date).
UbuntuOne tool started to work properly.
Now I suppose we should confirm that update resolves the issue (as for many users and me too).

BTW, after update this live USB stick installation told me it can't startup system (unable to find live filesystem).
