apt-get error on Fedora Core 4

[BFRD]

When trying to update the apt database I get the following:

[root@www network-scripts]# apt-get upgrade
rpmdb: Program version 4.3 doesn't match environment version
error: db4 error(-30974) from dbenv->open: DB_VERSION_MISMATCH: Database environment version mismatch
error: cannot open Packages index using db3 - (-30974)
error: cannot open Packages database in /var/lib/rpm
E: could not open RPM database

How do I go about fixing this?

TIA

The command to update the apt database is

apt-get update

, not

apt-get upgrade

Sorry, I copied the wrong thing (I tried that to see if it would help)

There must be something wrong with your apt installation. I recommend you use yum then instead of apt.
