trying to install rpm errors

[dandare]

hi..after installing pclinuxos on a spare drive opened a cli and typed

rpm -i bjfilter-common-2.50-2.i386.rpm

the rpm is in the current directory

this is error message

[root@localhost iP1500]# rpm -i bjfilter-common-2.50-2.i386.rpm
error: cannot get shared 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

ithis is the first time i have tried to do this so maybe i need to do something else first ..

You need to login as root to use RPM.
su -
(password)
# rpm -uhv bjfilter-common-2.50-2.i386.rpm
Or maybe PCLinuxOS uses sudo
sudo rpm -uhv bjfilter-common-2.50-2.i386.rpm
