error: cannot open Packages database in /var/lib/rpm
This is because of the corrupt rpm database on your server. There is a need to clean OR rebuild the repo on you server.
yum clean all
rm -f /var/lib/rpm/__db*
The above commands will remove rpm database packages and clean yum cache. Removing it won’t affect the current rpm’s installed.
Now, rebuild the rpm database with command below. It might take a while to rebuild it.
yum update –y
Now, update yum with command above and you are good to use rpm now. If you still face any issues, feel free to contact our support team & they will get rid of issues you face.
