i want to uninstall this application called synaptic which is a GUI for the apt-get program, but im running into some problems in doing so this is what i get when i try and uninstall the app:

[root@localhost Dan]# rpm -e synaptic-0.25-fr0.2rh73.i386.rpm
error: package synaptic-0.25-fr0.2rh73.i386.rpm is not installed

even though i know it is installed, my suspicions are confirmed whe i get this:
[root@localhost Dan]# rpm -ivh synaptic-0.25-fr0.2rh73.i386.rpm
Preparing... ########################################### [100%]
package synaptic-0.25-fr0.2rh73.i386.rpm is already installed

so then i try a different approach:
[root@localhost Dan]# rpm -q synaptic-0.25-fr0.2rh73.i386.rpm
package synaptic-0.25-fr0.2rh73.i386.rpm is not installed

then i try and update the app, hoping that the problem might correct itself in the update:
[root@localhost Dan]# rpm -Uvh synaptic-0.25-fr0.2rh73.i386.rpm
Preparing... ########################################### [100%]
package synaptic-0.25-fr0.2rh73.i386.rpm is already installed

I am soooo frustrated by this, and I am unaware of any other way to uninstall a RPM, so anyone who could give me there opinon as to what the problem is and a soulution would be greatly appreciated, thank you much.
