[ramana321388]

for installing softwares in ubuntu u require

for installing rpm packages like "amarok.rpm"
u require 'alien'

to get it from online repositories jus enter
$sudo apt-get install alien
now
$alien -i *.rpm
$dpkg -i *.deb
your package will be installed
for installing deb packages like amarok.deb just double click on it.
for installing source codes with 'tar.bz2' extension or 'tar.gz' u need
a utility called make

for this enter
$sudo apt-get install make
then
$tar -zxvf <package name>
$./configure
$make
$make install
hope ur package will be installed

Ubuntu is a Debian-based distro. So it's native package format is <package-name>.deb,
If the CD/DVD contains software packages in the RPM format, you must convert it
to Debian format using 'alien' package
Open the Terminal WIndow & type:
$ sudo apt-get install alien
Now wait for the installation to complete.
Use 'cd' command to move to different directory like in WIndows.
$ sudo alien <package>.extension
This will convert the package to Debian format.
If you are using Ubuntu 6.06 (Dapper Drake), just right-click on the package,
choose 'Open with 'GDebi Package Installer' & click on 'Install' button.
If you are using a older version of Ubuntu, then type this:
$ dpkg -i <package>.deb

For installing packages available as Source code in package.tar.gz2, or package.tar.gz
$ sudo apt-get install build-essential
$ gzip -d <package>.tar.gz2
$ tar -xvf <package>.tar
$./configure
$ make
$ sudo make install

This is the procedure.
@Ramana, the overall procedure you have given is correct, but there are minor mistakes!!
To compile from Source, you need C/C++ compilers,& make.
