Tutte le versioni di Ubuntu 14.04 “Trusty Tahr” e derivate: istruzioni per il download e l’aggiornamento.

Con l’uscita di una nuova release gli utenti si trovano davanti ad un enorme dilemma: aggiornare il proprio computer al nuovo rilascio per provare le ultimissime feature o rimanere cauti aspettando i primi bugfix continuando ad usare la vecchia release disponibile? Molti, avendo la fortuna di poter disporre di più computer o di un pc abbastanza potente e performante per poter far uso della virtualizzazione, non si porranno questo problema e procederanno subito all’aggiornamento. Questo breve articolo vi aiuterà ad effettuare l’upgrade del vostro computer nel modo più indolore possibile.

Le due vie percorribili sono le seguenti:

La prima è il download delle immagini ISO con masterizzazione del DVD (o “fabbricazione” di una pendrive) e successiva installazione tramite Live CD. Qualora i mirror siano sovraccarichi, o non vogliate servirvi di un CD, potrete optare per l’upgrade del vostro sistema pre-esistente tramite i seguenti comandi:

• Assicuratevi che il vostro sistema sia aggiornato: “sudo apt-get update && sudo apt-get dist-upgrade“
• Eseguite il vero e proprio passaggio di versione: “sudo update-manager -d“

Il comando sopra-citato (“update-manager -d”) sarà pienamente funzionante qualora la release che state utilizzando sul vostro computer sia esattamente quella precedente (Ubuntu 13.04) al rilascio odierno (Ubuntu 13.10). È generalmente sconsigliato eseguire l’upgrade tra due rilasci non consecutivi nel tempo per evitare problemi durante l’aggiornamento che potrebbero rendere il vostro pc instabile od addirittura non funzionante.

Qualora, quindi, stiate utilizzando un rilascio precedente ad Ubuntu 13.04 e siete desiderosi di aggiornare il vostro sistema, la procedura consigliata è sicuramente quella di una fresh re-install ponendo la necessaria attenzione ad eseguire i backup dei dati più importanti.

La nuova distribuzione Ubuntu 14.04 “Trusty Thar” avrà un supporto che durerà ben cinque anni.

Ubuntu 14.04 rappresenta la miglior soluzione che permetterà di avere questa integrazione tra smartphone, tablet e PC che si attendeva da molto tempo fra tutti i vari device che abbiamo a disposizione al giorno d’oggi.

Abbiamo diverse novità riguardanti anche la grafica di questo nuovo aggiornamento, infatti il team di Canonical ha lavorato moltissimo anche su questo fattore, aumentando la compatibilità con schermi ad alta definizione, ma questo è solo un piccolo assaggio.

Tuttavia ricordiamo che abbiamo a disposizione il classico ambiente desktop predefinito, che prende il nome di Unity, il quale è il fiore all’occhiello di Canonical, ottimizzato a livelli mai visti fino ad ora, permettendo di avere un’esperienza utente davvero eccezionale.
