Installing Totem with Synaptic

[Muralidhar Ganga]

Running Fedora Core 1.

Download two RPMS for apt and synaptic.

apt-0.5.15cnc1-0.fdr.3.1.i386.rpm and
synaptic-0.45-1.1.i386.rpm

To get Totem movie player:
Added two lines to /etc/apt/sources.list:
rpm http://rpm.livna.org/ fedora/1/i386 stable unstable testing
rpm-src http://rpm.livna.org/ fedora/1/i386 stable unstable testing

>From the synaptic GUI, 

"Update List", updated the repositories, found the Totem rpms,

Synaptic downloaded but failed to isntall because of signature 
failures:

Error: 0 unsigned packages
3 unknown signatures
0 illegal/corrupted signatures

Any ideas ?

Thanks
