Error: rpmdb open failed

Fix it doing the following commands:

# Take backup of rpm folder
cp -avr /var/lib/rpm/ /root/backups.rpm
# Remove RPM database files
rm -f /var/lib/rpm/__db*
#Verify the RPM db packages
db_verify /var/lib/rpm/Packages
# Rebuild the RPM database
rpm --rebuilddb
# Run yum clean to download repo data again
yum clean all
