When i run yum update on a server, i get error
[root@server ~]# yum update error: rpmdb: BDB0113 Thread/process 27693/140218146277184 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 [root@server ~]#
To fix this, you need to delete yum db files (__db.001, __db.002 and __db.003) from /var/lib/rpm folder.
rm /var/lib/rpm/__db.*
Run yum clean and update.
yum clean yun update -y
Now yum will work.
