Most of the time when we try to install a text editor or any software through yum or dnf we can see sometimes error like:
[root@server ~]# yum install telnet -y error: rpmdb: BDB0113 Thread/process 116647/139780789524352 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 Error: Error: rpmdb open failed [root@server ~]#So why this is happening? Through this error we can understand there is an issue with Berkeley DB Library. So here I came up with a solution you need to follow my steps from A-Z to make it work and read my steps carefully. Make sure before doing anything you have a backup of your server just for safety. Then login to your favorite ssh client then follow these steps.
Solution:
mkdir -p /var/lib/rpm/backup
cp -a /var/lib/rpm/__db* /var/lib/rpm/backup/
Remove corrupted database files:
rm -f /var/lib/rpm/__db*
Rebuild the RPM database:
rpm --rebuilddb
If you see any output like couldn’t removed or something then again run rm -f /var/lib/rpm/__db* then again run rpm --rebuilddb
You may need to clear the YUM cache and try again:
yum clean all
Finally now your yum should work try installing a text editor called nano type “yum install nano -y”
