dnf is a default command line to manage software on newer versions of fedora,in some cases when we kill the dnf process or an upgrade is interrupted there is a possibility of rpmdb currouption.
on my laptop when i killed the dnf process and reran update it was showing error error: rpmdb: BDB0113 Thread/process 3874/139621429724480 failed to fix the issue we need to rebuld the rpmdb.
1.cause of issue (kill 9 signal to dnf process a good example why not to use kill 9)
kill -9 3874 [1]- Killed dnf upgrade -y
2.Update the application cache
