Installing VirtualBox on Ubuntu

Install VirtualBox on Ubuntu 9.10 Karmic Koala


VirtualBox can run whole operating systems "in a window," but that do not have direct access to your computer hardware. VirtualBox can run all versions of Windows, Linux, and various other x86 and AMD/Intel 64 bit systems. Some versions of Linux are optimized to run in a virtual environment, but any will work.

Requirements
-----------------

At first, you need to configure and activate the correct repositories to install VirtualBox. Follow the steps:

1. For GNOME, Go to: System > Administration > Software Sources
For KDE, go to: System Settings > Add and Remove Software > Settings > Edit Software Sources
2. Go to "Other Software" tab.
3. Add: deb http://download.virtualbox.org/virtualbox/debian karmic non-free

Now import the package signing key, using the command:

wget -q http://download.virtualbox.org/virtualbox/debian/sun_vbox.asc -O- | sudo apt-key add -

Installation
---------------

Pretty simple! Run the following command. You may also click on the linked package name:

sudo aptitude install virtualbox-3.1

Use
-----

Now you need to add yourself to the required group. This facilitates access to the vboxdrv system device. Use the following command to add yourself to the required group:

sudo gpasswd -a vboxusers

Once you have applied this change you will need to logout and log back in. This is required for the group-access change to take effect.

After you are logged back in you should be able to successfully launch VirtualBox from: Applications > System Tools > VirtualBox

Enjoy VirtualBox!! :D

Use your browser to install packages on your ubuntu (using apt: or http://appnr.com)

In Ubuntu, you can install packages in many ways. You can either use command line instructions in terminal or you can use the synaptic package manager for adding/removing packages.

There’s another way! You can do so from your web browser (like firefox etc.). Just visit http://appnr.com and here you’ll find all the necessary softwares, categorized according to need. Just click on the software you need, it will be installed to your system. Sounds easy? It really is!

Well, there’s another way! You can directly install any package with the help of your browser. On the address bar, write apt: and then the name of the software you want. For example, suppose you want to install VLC medial player; then write apt:vlc. Then it’ll be installed. It seems little bit like the command line, but it’s far easier as long as you know the package name. This particular feature is available in all the versions following ubuntu 7.10.

How to set environment variables in Ubuntu Linux

Here you can learn how to set up environment variables on Ubuntu.

Please follow the simple following steps:

1. Go to:

Applications > Accessories > Terminal

to open the terminal window.

2. You should take a back up of /etc/profile file. So write the commands:

sudo cp -p /etc/profile /etc/profile_backup

3. Now, to edit the /etc/profile file, write the following command in the terminal:

gksudo gedit /etc/profile

The file will be opened for editing.

4. You have to add one line at the end of the file. That line will tell the name of the variable and it's value.

Format for this command is:

export ENV_VARIABLE_NAME=VALUE

where ENV_VARIABLE_NAME is the name of the variable and VALUE is the value.

For example,

export JAVA_HOME=/mnt/F/ubuntu/j2sdk1.4.2_16

here /mnt/F/ubuntu/j2sdk1.4.2_16 - this path is the value of the variable JAVA_HOME.

5. Save your file and close it.

6. Restart your machine.

7. You can check if the value is properly set with these commands:

cd $JAVA_HOME
pwd
