Ubuntu One is a famous cloud storage service which comes pre-installed with Ubuntu. Despite being an excellent synchronization service, it is unable to match Dropbox due to lack of a few features. One of these features include the absence of an app-indicator menu applet. For this reason, one requires using third-party applications like Magicicada to view real time synchronization stats. Ubuntu One Indicator is an app-indicator applet which displays Ubuntu One synchronization stats from the system tray. This applet is quite similar to the Dropbox indicator for Ubuntu, with the additional feature of showing real time statistics for files being synced with the Ubuntu One server.
To install Ubuntu One Indicator, add the below PPA To Software Sources. If you do not know how to add a PPA to Software Sources, then see my post: How To Add PPA To Software Sources In Ubuntu Linux From Ubuntu Software Center.
Alternatively, you can enter this command in the Terminal to add the PPA:
sudo add-apt-repository ppa:rye/ubuntuone-extras
Once the PPA is added, enter the following command in the Terminal.
sudo apt-get install ubuntuone-indicator
After installation, you will require launching the Ubuntu One Indicator to initiate the synchronization process. You can click on the app-indicator menu icon to view the files being synchronized. The synchronization process can be discontinued anytime from the Disconnect option.
You can download the Ubuntu One Deb packages from the Launchpad link give below. The packages are available for Ubuntu 10.04, 10.10, 11.04 and Ubuntu 11.10 Oneiric Ocelot.
