Ubuntu 1431浏览

Only one more day to go to get the stable version of Ubuntu 14.04 Trusty Tahr. Yes, Ubuntu 14.04 Trusty Tahr will be released on April 17th, 2014. Like all of the avid fans of Ubuntu, I hope Ubuntu 14.04 will come with a lot of improvements and new features than Ubuntu 13.10 Saucy and the previous versions. Everybody is curiously waiting to see what Ubuntu 14.04 will offer to Ubuntu lovers. Ubuntu 14.04 Final beta is already out a couple of days before, and you can read the complete news here.

Do you have Ubuntu 13.10, 13,04, 12,10 or 12.04 Precise Pangolin or older version of Ubuntu on your system, and want to upgrade to this new release? I know you wish. Just follow the simple steps below, you can easily upgrade from Ubuntu 13.10 to Ubuntu 14.04 Trusty desktop and as well as Server edition. Please note that you can’t upgrade from 13.04 to 14.04 directly. Instead, first upgrade from 13.04 to 13.10, and then upgrade from 13.10 to 14.04. Clear? Good. Let us get through into the upgrade process. Don’t worry, it’s too simple to follow.

Though, the steps provided below is for Ubuntu 14.04, It may work for other Ubuntu derivatives such as Lubuntu 14.04, Kubuntu 14.04 and Xubuntu 14.04 as well.

Important: Before proceeding to upgrade, make a full backup of your data to an external device (USB stick or CD/DVD).

Before going to upgrade, we need to update the system. Open up the Terminal and enter the following commands.

The above command will download and install the available latest packages.

Important: The upgrade process got failed at the first time for me. However, I restarted the upgrade process again, and everything went fine. Finally, I got the fresh Ubuntu 14.04 LTS on my Laptop. I hope this will not happen on the stable version.

Server Upgrade

To upgrade from Ubuntu 13.10 server to Ubuntu 14.04 server, do the following steps.

Install the update-manager-core package if it is not already installed:

sudo apt-get installupdate-manager-core

Edit the file /etc/update-manager/release-upgrades,

sudo nano /etc/update-manager/release-upgrades

and set Prompt=normal or Prompt=lts as shown below.

# Default behavior for the release upgrader.

[DEFAULT]
# Default prompting behavior, valid options:
#
#  never  - Never check for a new release.
#  normal - Check to see if a new release is available.  If more than one new
#           release is found, the release upgrader will attempt to upgrade to
#           the release that immediately succeeds the currently-running
#           release.
#  lts    - Check to see if a new LTS release is available.  The upgrader
#           will attempt to upgrade to the first LTS release available after
#           the currently-running one.  Note that this option should not be
#           used if the currently-running release is not itself an LTS
#           release, since in that case the upgrader won't be able to
#           determine if a newer release is available.
Prompt=lts

Now, it is time to upgrade your server system to latest version using the following command:

sudo do-release-upgrade -d

Follow the on-screen instructions. You’re done!!.

Cheers!!
