Red Hat

When i try to install rpm with rpm -ivh ntp* it shows package is already install and when i query for same package it shows package is not installed ?How to resolve DSA signature error for rpm? How to choose rpm package except redhat version(el5) and architecture(i386) and site link for that?

Please show exact command and resulting output for both operations. Without seeing exactly what you are doing, it is hard to help you.

These are the command i tried and their output
1] rpm -ivh ntp-4.2.2p1-15.el5.centos.1.i386.rpm
o/p: Package is already installed
2] rpm -q ntp-4.2.2p1-15.el5.centos.1.i386.rpm
o/p: Package is not installed.
3] rpm -ivh fuse-2.7.4-8.el5.i386.rpm
o/p: DSA signature error no key keyid
4] mount sharefolder -t vboxsf /mnt
o/p: No filesystem vboxsf

That is the expected output. You are confused about the difference between a package filename and a package name. Sometimes you have to use a package name and sometimes you have to use a package filename.

For example:

Code:

$ rpm -q bash-3.2-32.el5.rpm
package bash-3.2-32.el5.rpm is not installed
$ rpm -q bash
bash-3.2-32.el5

Can anyone please guide me the step to install rpm with rpm command
1] url to download rpm
2] how to check right rpm for your system
3] what to do if conflict occur while installation of package
4] how to overcome dependency
5] how to resolve dsa signature error
6] url for driver package

Before you go the long way around the block, here, check to see if the package is in the yum repo. Trust me, it saves time.

OK, I just did a quick check, and on my Fedora system (which is just an cutting-edge RedHat system), the package (fuse) is already installed.

And NTP is in the yum repo.

Code:

yum install ntp

Maybe you have an uncompleted install?
