problems at installing apt

[chun lee]

hi there:

i am trying to install apt on my Fedora and got these errors and i don't
know what they mean and how to solve it. could anyone give me some
advice? 

i typed:

   rpm -Uvh apt-0.5.15cnc2-1.rhfc1.ccrma.i386.rpm

and i got:

   error: cannot get exclusive lock on /var/lib/rpm/Packages
   error: cannot open Packages index using db3 - Operation not permitted (1)
   error: cannot open Packages database in /var/lib/rpm

also:

   rpm -Uvh apt-devel-0.5.15cnc2-1.rhfc1.ccrma.i386.rpm
   error: Failed dependencies:
        apt = 0.5.15cnc2-1.rhfc1.ccrma is needed by apt-devel-0.5.15cnc2-1.rhfc1.ccrma

many thanks

yours
