Pidgin PPA Ubuntu

The instant messaging program Pidgin 2.10.9 has been released recently. It mainly fixed problems logging into some servers including jabber.org and chat.facebook.com.

The default Pidgin versions in Ubuntu universe repositories are quite old (See Pidgin changelog history). The Pidgin Developers PPA provides the most recent version of Pidgin for Ubuntu 14.04, Ubuntu 13.10, Ubuntu 12.10, and Ubuntu 12.04. Here’s how to add the PPA and install / upgrade your Pidgin from it.

Install the latest Pidgin Release in Ubuntu

To get started, press Ctrl+Alt+T on your keyboard to open the terminal. When it opens, run the command below to add Pidgin PPA to your system:

sudo add-apt-repository -y ppa:pidgin-developers/ppa

After that, update your system package lists and then you’re able to install packages from the PPA:

sudo apt-get update

Now install the Pidgin:

sudo apt-get install pidgin

That’s it. Enjoy!

For the Off-the-Record (OTR) plug-in, which is designed for use with Pidgin ensures authenticated and secure communications between Pidgin users, just search for and install pidgin-otr from Ubuntu Software Center. Finally enable the plugin from Pidgin menu Tools -> Plugins.

VLC 2.1.2 Ubuntu 12.04

 
The popular VLC media player has reached version 2.1.x with some fantastic new features, bug fixes and performance improvements. However, the official PPA for Ubuntu 13.10 and earlier is stuck at version 2.0.8.

There’s now a third-party PPA that provides the most recent build of VLC (it’s 2.1.2 so far) to Ubuntu 12.04, Ubuntu 12.10, Ubuntu 13.04, and Ubuntu 13.10 users. The PPA is maintained by djcj

install vlc 2.1.2 ubuntu 13.10

The PPA is not officially endorsed, supported or otherwise backed by the Videolan team. Use it at your own risk!

Press Ctrl+Alt+T on your keyboard to open the terminal. When it opens, run the commands below to add the PPA and install VLC.

sudo add-apt-repository ppa:djcj/vlc-stable

sudo apt-get update

sudo apt-get install vlc

If you don’t like the PPAs, directly download & install the DEBs from the launchpad page.

Upgrade From Ubuntu 13.10 to Ubuntu 14.04

This simple tutorial shows how to upgrade your system from Ubuntu 13.10 Saucy to Ubuntu 14.04 Trusty Tahr for both Desktop and Server editions.

Ubuntu 14.04 Trusty is scheduled to be released on April 17th. At the moment of writing this article, the alpha release is available to upgrade in Saucy’s updater for testing purpose.

Important: Production machines please wait until the Ubuntu 14.04 final is released. By then, we can follow below steps to upgrade our systems.

Before starting any upgrades, you need to:

  • Backup important files, documents, bookmarks and other data.
  • If you’ve manually installed proprietary drivers directly from the manufacturer’s website, then before upgrading I recommend removing these drivers first and reverting to the open-source drivers
  • Open Software & Updates utility from Unity Dash. Disable all third-party repositories under Other Software tab.

Desktop Upgrade:

Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, run the commands below to update your system:

sudo apt-get update; sudo apt-get dist-upgrade

Now start the updater via -d option:

sudo update-manager -d

The Software Updater will open and tell you your system is up to date and a new release Ubuntu 14.04 is available.

upgrade from Ubuntu 13.10 to Ubuntu 14.04

Click on the Upgrade button and confirm again in next window. Software Updater will fetch and install the files and prompt you to remove unnecessary applications.

Finally you’ll be asked to restart your computer to finish the upgrade. That’s it.

Upgrade Ubuntu Server:

NOTE: Please backup your configuration files if you’re running any services on Ubuntu server.

For Ubuntu Server edition, we need to install the update-manager-core first by executing the command below:

sudo apt-get install update-manager-core

Then edit the config file:

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

Make sure there’s a line that says “Prompt=normal” or “Prompt=lts”.

Start the upgrade process by:

sudo do-release-upgrade -d

Follow the on-screen prompts and you’re done!.
