how to rebuild the RPM database

If rpm / yum command hangs incessantly during operations or you see error messages, it likely means your RPM database has become corrupted.

/var/lib/rpm/ stores the RPM database information, so to resolve you can just delete and rebuild the database using one of the two methods below like so:

Method # 1

rm -f /var/lib/rpm/__db*
rpm –rebuilddb -v -v

Method # 2
If you are still getting errors, then try your luck with following commands:

# mv Packages Packages-BAKUP
# db_dump Packages-BAKUP | db_load Packages
# rpm -qa
# rpm –rebuilddb
