Firstly i am not able to setup anything on linux and i am crazy now. Neither openoffice nor flash player i spend 3 whole day and i cannot set them up.
sometimes it says there is no such a command for rpm.
is it possible for my Ubuntu 7.04 have missing commands.
if it is yes how can i update them.
please help me give me some advices some links or pdf book .

First of all, Ubuntu is a Debain derivative, and can not use .rpm files. You need to set up Synaptic, the package manager for on line respritories. Once that is done, install OO, using Synaptic. It will look after any dependencies, and get you the latest stable release.

I do not think you are missing commands, other than the rpm installer. You will not have it because you are using Ubuntu.

Post back if you need help setting up Synaptic. There are some tutorials on Ubuntu's site.

I can't believe OO isn't already installed (applications - office)
If it isn't, go to Applications - Add/Remove and do a search... Loose the habit of searching the internet for program installers!

Look here for instruction to install the flash player.

Just to echo what has been said already, you appear to be downloading software from the internet like you do with Windows. That method went out of date about a decade ago in the Linux world. Use > Applications > Add/Remove Programs or > System > Administration > Synaptic Package Manager.

That is not only easier (you don't have to track down software and hassle with installing it) it is also better because Ubuntu will manage your software for you, putting everything in the right place, making sure you have the latest updates and security fixes, and preventing any conflicts.

If you correctly installed Ubuntu 7.04, then Open Office would have been on your applications menu. And if you were able to use Ubuntu at all, then you at least were able to get the live CD version working. Therefore, you should have been able to see the open office suite on the application menu. It would have appeared on the

Applications->Office->etc

pulldown menu.

The advice to use Synaptic is very good. This package will help you with finding other packages that you may want to install. To start using it, you will note there is a "search" button on the top right of the menu bar. With this, you can search for all packages containing specific words of interest. For instance, if you typed "office" into the popup and let it go, it will think for a while (and make sure your computer is connected to the internet when you do this). Eventually it will display a list of all packages whose descriptions(?) contain the word "office". Some may have a green checkmark on the left of the window and these are packages which are already installed on your computer. Those whose checkmark field are blank are not installed. If you want, you can check the box and then apply the change. Synaptic will fetch all the files needed to install that package while you sleep/eat/daydream/thumb your nose at Bill Gates, whatever. When it's complete, the requested packages *should* be installed and ready to run. No fuss, no muss.

If you are new to Linux, you may want to narrow your search a bit. The "office" keyword I used as an example will give you dozens of choices. So instead, typing "OpenOffice" might be a better choice. You will still have to sort through a large number of choices, but not as many as the first search. Google is a good tool for ferreting out which of the displayed choices you might actually want. Failing that, there is always this forum.

thank you all. i will try all of them.

PS:

It seems that it is very common for newcomers to miss the package manager / repository paradigm that is one of the huge strengths of Linux.

Perhaps distros should boot up with an introduction to the package manager.....
