Ubuntu One is an OpenID-based single sign-on service operated by Canonical Ltd. to allow users to log onto many Canonical-owned websites. Until April 2014, Ubuntu One was also a cloud storage service and music store which allowed users to store data within the cloud.
The service enabled users to store files online and sync them between computers and mobile devices, as well as stream audio and music from cloud to mobile devices.
In April 2014, Canonical announced that the cloud storage and synchronization features would be shut down later that year, leaving the sign-on features intact.
Ubuntu One has a client application that runs on Ubuntu 9.04 and later or Windows XP or newer, and Mac OS X 10.6 and higher. Other Linux distributions not running GNOME are supported through a console client. The source code is available through launchpad and can easily be compiled for other Unix-like operating systems such as FreeBSD. There is an Ubuntu One music app for iOS devices. A free Ubuntu One account offers 5 GB of storage.
The Ubuntu One service is similar to services such as Microsoft OneDrive, iCloud, Dropbox, Google Play Music, Amazon Cloud Player. Its client code is written in Python. It uses Twisted for its low-level networking and Protocol Buffers for protocol description. Data is synced over a custom protocol called "u1storage", and stored on Amazon S3.
Ubuntu One offers automatic upload of photos taken from Android mobile devices for immediate sync across computers; integration with Mozilla Thunderbird for contacts and with Tomboy for notes due to the access to the local CouchDB instance. It also has capabilities for purchasing DRM-free music while synchronizing them automatically with an Ubuntu One Account via the Ubuntu One Music Store (in partnership with 7digital).
Ubuntu One publishes APIs for developers wishing to build applications with file and data synchronization or music streaming.
An Ubuntu One account gives users access to the Canonical Store, Launchpad, Ubuntu One and other Ubuntu services; an Ubuntu One account allows users to store files within the cloud, store their contacts details within the interface, access the Ubuntu One Music Store to buy music from and activate the Ubuntu Software Center. Other sites that support OpenID authorization also have support for Ubuntu One.
On June 2013, the Ubuntu Single Sign On account was re-branded under Ubuntu One as part of consolidating Canonical's online services under the Ubuntu One brand. Also, the announcement identified Ubuntu Pay as another service to come under the brand. Following a hack in 2013, Canonical put the Ubuntu Forums under the brand, meaning that Forum users now log in using Ubuntu One rather than with the previous username-password system.
On April 2, 2014, Canonical announced shutting down of select Ubuntu One services. As of the day of announcement, it is no longer possible to purchase storage or music. File services will be unavailable from June 1, but existing users will be able to download their content until July 31, when all stored data will be permanently deleted. Canonical explained that they are not willing to make more investment in Ubuntu One which would be required to compete with other services. Instead, their priority is making a "converged operating system for phones, tablets, desktops." The company also announced plans to release the source code for the Ubuntu One server software to the public under an open-source license. The shutdown of cloud storage and synchronization services will not affect the single sign-on function of Ubuntu One, which will remain in place.
The Ubuntu One App has a 4.5 star (out of 5) rating on the iTunes App Store, and 4.5 star (out of 5) rating on Google Play. It had a 4.5 star (out of 5) rating on the Chrome Web Store, until it was taken off the site.[when?]
There is not yet a native client integration for the Kubuntu variant of the Ubuntu operating system, as of January 2013. Kubuntu integration is under development and has also received a grant from the Google Summer of Code 2010.
Further criticism concerns the unclear revenue share that will be granted to the community. The Amarok development team has announced that they will not add support for the Ubuntu One Music Store to the Amarok media player for the moment, unlike the Magnatune media store, which returns 10% of the revenue produced via the interface to Amarok.
