rpm command won’t work:

I tried to install some xml related rpms on my Fedora, so checked yum list to see what xml rpms are installed. But the system gave me the below error.

[[email protected] home]# yum list | grep -i xmlrpmdb: Thread/process 31902/140347322918656 failed: Thread died in Berkeley DB libraryerror: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recoveryerror: cannot open Packages index using db3 -  (-30974)error: cannot open Packages database in /var/lib/rpmCRITICAL:yum.main:Error: rpmdb open failed[[email protected] home]#

Tried fixing using “yum clean”

I initially thought it was some issue with yum and its cache, so tried yum clean. That did not work!.

Corrupted rpmdb:

Taking a closer look, it sounded like rpm db is corrupted. This caused issues in rpm command.

Delete and Rebuild rpmdb:

Deleted the __db* files and did a “rpm –rebuilddb”. It worked perfectly and I was able to do rpm and yum commands.
