CentOS: rpmdb: PANIC: fatal region error detected; run recovery error and solution

by

The error “rpmdb: PANIC: fatal region error detected; run recovery” occurs when the RPM database becomes corrupted. This can happen for various reasons, including system crashes, disk failures, or incomplete transactions.

To resolve this issue, you can run the rpm --rebuilddb command as follows:

  1. Stop any applications that might be accessing the RPM database.
  2. Backup your existing RPM database files, typically located in the /var/lib/rpm directory, just in case.
  3. Run the following command to rebuild the RPM database:
sudo rpm --rebuilddb
  1. Restart any applications that you stopped in step 1.

If this solution does not work, you can try reinstalling the RPM package. This will create a new RPM database and should resolve the issue. (Ambien)

sudo yum reinstall rpm

These steps should resolve the “rpmdb: PANIC: fatal region error detected; run recovery” error and allow you to use yum and other RPM-based tools without problems.
