I'm getting this error msg:

rpmdb: fatal region error detected; run recovery error: db4 error(-30982) from dbenv->open: DB_RUNRECOVERY: Fatal error, run database recovery error: cannot open Packages index using db3 - (-30982) error: cannot open Packages database in /var/lib/rpm

How can i fix it?

Thanks!

whatever the command is to rebuild your rpm database, I forget because I don't use redhat.

rpm --rebuilddb
??
