To resolve this key problem in RHEL, I installed the public release key

#rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

This allows you to install from the local source.Copy and install all the packages from the RHEL5 DVD’s to a directory to use ‘YUM’ from local repository.

Importing the key as outlined above enabled me to install the packages without getting the following error:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 37017186.

Note : RHEL DVD’s help me in completing the installation in local server without internet connection.

It is very easy and simple to install Compiz & Compiz Fusion plugins on Lucid Lynx.

Just Click Application —> then Ubuntu Software Center

Ubuntu Software Center pop up

Search for CCSM

Click install and then give the root password to install CCSM

Installation Progress

After the CCSM installation completed, install Nvidia drivers

Click System –> Administration –> Hardware Drivers

Then the system searched for available drivers and i choosed the recommended Nvidia accelerated graphics driver (version 173) option from the list and then activated the driver by clicking Activate button.

Restart the system, so that the new nVidia graphic display driver will be ready for use.

Then enabled the desktop effects by clicking System –> Preferences –> Appearance and on the –> Visual Effects tab, selected Normal .

After this installation my desktop looks great, very much happy to use Desktop effects in Ubuntu 10.04.

After reading this you too will be enjoy using  Compiz & Compiz Fusion plugins in Ubuntu 10.04 (Lucid Lynx).

After I install Ubuntu 10.04 , I found the new default theme has the Minimise, Maximise and Close buttons have been moved from the top right, to the top left.

It is very difficult for me to use these buttons on the left.

Now, How do I move the Minimise, Maximise and Close buttons Back to the Right  ?
To move now Press Alt+F2 , enter “gconf-editor” in the text field, and click on Run.

The Configuration Editor should pop up.

Click on the + button next to the “apps” folder, then Click “metacity” in the list of folders and then click on the “general” folder.

Double-click button_layout to edit it on the right side .

Change the text in the Value text field to:


Click OK and the change will occur immediately.

Now you will see the Minimise, Maximise and Close buttons have been moved to top right.

Now it is really good see the buttons back to top right, and after reading this you too feelto move the Minimise, Maximise and Close buttons back to the Right in Ubuntu 10.04 .

It is very simple.

Click Application –> Ubuntu Software Center –> Get software

Now gimp installed in my PC and it works fine.

I Love GIMP.

I decided to install Ubuntu 10.04 (Lucid Lynx) in PC today and the outlook looks good. I was very much surprised that “GIMP” was missing in this release and then I tried to update Lucid Lynx.

verman@verman-desktop:~$ sudo apt-get update
[sudo] password for verman:

Err http://security.ubuntu.com lucid-security Release.gpg
Something wicked happened resolving ‘security.ubuntu.com:http’ (-5 – No address associated with hostname)
Err http://security.ubuntu.com/ubuntu/ lucid-security/main Translation-en_IN
Something wicked happened resolving ‘security.ubuntu.com:http’ (-5 – No address associated with hostname)
W: Failed to fetch http://in.archive.ubuntu.com/ubuntu/dists/lucid-updates/multiverse/source/Sources.gz  Something wicked happened resolving ‘in.archive.ubuntu.com:http’ (-5 – No address associated with hostname)

E: Some index files failed to download, they have been ignored, or old ones used instead.

This Showed me a error “No address associated with hostname” in all the line.

Then I tried all the possibility to update  Lucid Lynx.

I was using Proxy Internet connect and  I didn’t touch any settings.

Proxy is working fine and able to browse all website in the Internet.

Then suspect it has nothing to do with proxy .

Even when i manually exported  HTTP proxy: http://myname:mypassword@proxy Port: 8080 , apt-get update was not working.

After a long search using my friend google, I found that we had to acquire http proxy in apt.conf file

Then I just added a line in /etc/apt/apt.conf

Acquire::http::Proxy “http://myname:mypassword@proxy:8080”;

after that it worked charm!

verman@verman-desktop:~$ sudo apt-get update

Thanks to Google ……….

Now I will try installing “GIMP”
