I see in some topics that to install ubuntu-one, I've to execute these commands :

sudo add-apt-repository ppa:apachelogger/ubuntuone-kde
sudo apt-get update
sudo apt-get install ubuntuone-kde

However, it don't work (Is ppa:apachelogger/ubuntuone-kde closed ?) :

sudo add-apt-repository ppa:apachelogger/ubuntuone-kde

How could I install ubunto-one on KDE and use it with dolphin ?
