Yesterday I did an up2date and it installed fine then a little bit later I updated all my packages using apt-get. I am in Fedora Core 3 and now I am attempting to install adobe reader and this is what I get:
rpm -Uvh '/home/paul/AdobeReader_enu-7.0.0-2.i386.rpm'
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
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 database in /var/lib/rpm

I cannot do anything that has to do with rpm files. Any ideas?
Thanks in advance,
Paul

nevermind i figured it out. I fixed it using the following command:
rm /var/lib/rpm/__* && rpm --rebuilddb
