I have already used "apt-get insatll rpm" in Debian 3.1a.
But when I used rpm -ivh XXXX.rpm, the XXXX package can't be installed. And the error message showed below:

## error: cannot open package index using db3
## error: cannot open package database in var/lib/rpm

actually, there is no any rpm folder in /var/lib

please help me!!

Thanks a lot!!
