How To Solve “Error: rpmdb open failed” Error In CentOS

Solve Error: rpmdb open failed Error In CentOS

Today, I was testing Nginx web server in a CentOS 7 VM. In the middle of the update process, the power has gone. Since I don’t have any UPS, my host system went down immediately. After few minutes, the power came, and I turned on the VM again and started the upgrade process. When I run the “yum update” command, I get this:

error: rpmdb: BDB0113 Thread/process 2196/139984719730496 failed: BDB1507 Thread died in Berkeley DB library
error: db5 error(-30973) from dbenv->failchk: BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db5 - (-30973)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Error: rpmdb open failed

Seems like YUM broke down. I couldn’t run any yum command. I haven’t faced this error before, and I didn’t know what to do. So, I headed over to the CentOS forum hoping to find a suitable solution to fix this issue. After a few searches over the forum, luckily I found a workaround. If you ever got into this problem, look nowhere and just do the following steps.

First backup the rpm database using command:

# mv /var/lib/rpm/__db* /tmp

Then, run the following command:

# yum clean all

Then, run the update again:

# yum update
