Con il rilascio della versione beta di Ubuntu 10.04 Lucid Lynx si entra infatti nel periodo finale del ciclo di sviluppo; da qui ad Aprile le uniche modifiche ai pacchetti permesse saranno le correzioni ad eventuali bug scampati alle precedenti alpha.

Il rilascio definitivo è previsto per il 29 aprile 2010.

L'annuncio ufficiale:

The Ubuntu team is pleased to announce the first beta release of Ubuntu 10.04 LTS (Long-Term Support) Desktop, Server, and Netbook editions and of Ubuntu 10.04 Server for Ubuntu Enterprise Cloud (UEC) and Amazon's EC2.
Codenamed "Lucid Lynx", 10.04 LTS continues Ubuntu's proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution.

Ubuntu 10.04 LTS Desktop and Netbook Editions continue the trend of ever-faster boot speeds, with improved startup times and a streamlined, smoother boot experience.

Ubuntu 10.04 LTS Server Edition provides even better integration of the Ubuntu Enterprise Cloud, with its install-time cloud setup.

Ubuntu 10.04 LTS Server for UEC and EC2 brings the power and stability of the Ubuntu Server Edition to cloud computing, whether you're using Amazon EC2 or your own Ubuntu Enterprise Cloud.

The Ubuntu 10.04 family of variants, Kubuntu, Xubuntu, Edubuntu, Ubuntu Studio, and Mythbuntu, also reach beta status today.

Desktop features
----------------

Social from the start: We now feature built-in integration with Twitter, identi.ca, Facebook, and other social networks with the MeMenu in the panel.

New Design: Cleaner and faster boot, new notification area, new themes, new icons, and new wallpaper bring a dramatically updated look and feel to
Ubuntu.

Ubuntu One: Choose any folder in your home directory to sync, choose from millions of songs for purchase in the Ubuntu One Music store.

Please see http://www.ubuntu.com/testing/lucid/beta1 for details.

Server features
---------------


Cloud computing: The Ubuntu Enterprise Cloud installer has been vastly improved in order to support alternative installation topologies. UEC components are now automatically discovered and registered, even with complex topologies. Finally, UEC is now powered by Eucalyptus 1.6.2 codebase.

UEC and EC2: Ubuntu 10.04 LTS continues the tradition of official Ubuntu Server image releases for UEC and for Amazon's EC2, giving you everything you need for rapid deployment of Ubuntu instances in a cloud computing environment. UEC images, and information on running Ubuntu 10.04 on EC2, are available at:

http://uec-images.ubuntu.com/releases/10.04/beta1

Stability and security: Ubuntu 10.04 LTS brings many improvements over Ubuntu 8.04 LTS to keep your servers safe and secure for the next five years, including AppArmor profiles for many key services, kernel hardening, and an easy-to-configure firewall.

Ubuntu Netbook features
-----------------------
Ubuntu Netbook Edition is optimised to run on Intel atom based netbooks. It includes a new consumer-friendly interface that allows users to quickly and easily get on-line and use their favourite applications. This interface is optimised for a retail sales environment.

It includes the same faster boot times and improved boot experience as Ubuntu desktop.

Kubuntu features
----------------

Kubuntu 10.04 LTS will be the first LTS to feature KDE 4 Platform and Applications. KDE 4 has come a long way since its early releases and is now suitable for the high demands of LTS users. Being an LTS we have focused on bug fixing and stability for this release, but we did find time to add features such as touchpad configuration, Firefox KDE integration, Kubuntu notification improvements, and cross-desktop systray menu standardisation.
Kubuntu features the Plasma Desktop while Kubuntu Netbook Remix comes out of preview status with the Plasma Netbook workspace.

See https://wiki.kubuntu.org/LucidLynx/Beta1/Kubuntu for more details.

Edubuntu features
-----------------

Edubuntu in Lucid features a more complete live environment containing more software from universe and all existing language packs as well as our usual educational software in their current version. For Lucid the text installer has been removed and so is LTSP for the time being. We expect to have LTSP back on the DVD for the next beta. The DVD is then much smaller than it used
to be but will still provide a complete education environment based on Ubuntu Lucid.

Also included on the Edubuntu DVD is a small repository containing the required packages to transform the regular Edubuntu desktop into a LTSP server or install the Netbook edition interface.

Mythbuntu features
------------------

Mythbuntu 10.04 introduces MythTV 0.23. This new version is significantly faster and should feel more responsive and stable than older versions. It also integrates better into the OS with better support for things like ConsoleKit and Upstart.

Please see http://www.mythtv.org/wiki/Release_Notes_-_0.23 for more details about changes introduced in 0.23.

See http://mythbuntu.org/10.04/beta for information about the Mythbuntu beta release.

Other
-----

* On the Desktop: GNOME 2.30, KDE SC 4.4, XFCE 4.6.1, OpenOffice.org 3.2.0, X.Org server 1.7.5

* On the Server: Apache 2.2, PostgreSQL 8.4, PHP 5.3.1, LTSP 5.2

Le principali attività per collaborare sono:

* Sviluppo: nella struttura Launchpad ogni programmatore può inserire caratteristiche o sviluppare il codice di ogni applicazione usando il sistema di controllo delle versioni Bazaar.
* Documentazione: si possono documentare nella propria lingua le applicazioni attraverso i forum internazionali, locali o attraverso Launchpad (con il progetto Rosetta).
* Traduzione: attraverso i forum internazionali o locali o attraverso Launchpad si può contribuire alla traduzione delle applicazioni.
* Supporto: i nuovi utenti possono ottenere supporto attraverso Launchpad o sui forum.
* Nuove idee (Idea Pool): attraverso Launchpad o sul sito internazionale si possono richiedere nuove caratteristiche o richieste particolari su nuove opzioni nelle future versioni di Ubuntu. Gli sviluppatori usano i suggerimenti per progettare le caratteristiche future della distribuzione. Da Febbraio 2008 è stato istituito il sito "Ubuntu brainstorm" che raccoglie le idee, i desideri e i suggerimenti degli utenti del sistema.

Con programmi come Ubuntu Customization Kit, Remastersys oppure Reconstructor si possono creare LiveCD personalizzati di Ubuntu, aggiungendo funzionalità o rimuovendo programmi non utilizzati.

Una delle critiche più forti a Ubuntu, e su Linux in generale, è il limitato supporto per alcuni tipi di hardware, come alcuni modelli di stampanti multifunzione, penne wireless, schede video, scanner e webcam economiche. Inoltre, non sono supportati o necessitano di pesanti lavori di configurazione i cosiddetti "WinModem", Modem analogici intregrati nelle schede audio, tale mancanza impedisce l'uso di Internet su Ubuntu nelle zone senza copertura ADSL o GPRS/UMTS/HSDPA Il problema è comune a tutte le distribuzioni Linux e deriva dal mancato supporto da parte dei costruttori e dei distributori di hardware. Alcuni di essi infatti non forniscono i driver o le specifiche dei loro dispositivi.

Su sistemi operativi proprietari, come Windows, il sistema si avvale della presenza di driver appositamente realizzati per interagire con i vari dispositivi. In ambito Linux, invece, i driver vengono scritti dagli sviluppatori, possono quindi tardare a essere rilasciati e, in alcune occasioni, mancare del tutto. Sono da rimarcare le differenze di installazione dei driver tra un sistema Linux e un sistema proprietario quale Windows. Mentre un sistema Windows deve usare i driver forniti dal costruttore del dispositivo, in Ubuntu questi driver sono già "integrati" e salvo eccezioni il dispositivo viene riconosciuto e utilizzato senza l'intervento dall'utente. Se il driver manca si può chiedere assistenza sui forum o in rete. In taluni casi si è costretti a non poter utilizzare il dispositivo, fino a nuovo aggiornamento del kernel.

Alcuni driver per Windows si possono usare su Ubuntu usando un software chiamato NDISwrapper, spesso utilizzato per i dispositivi wireless.

Il sito ufficiale raccomanda di usare solo hardware supportato ed evitare di comprare dispositivi i cui costruttori non rilasciano specifiche o driver, dato che questo comportamento limita la scelta dell'utente finale a usare software libero. Il problema è sempre "tenuto sotto controllo" da continui aggiornamenti del Kernel Linux il quale, ad ogni rilascio, aumenta il numero di dispositivi hardware supportati.
