In this post I am sharing, the troubleshooting step of the error which we found on using linux yum command.Error: database disk image is malformed, we found this problem running the command yum update
To resolve this issue run the below given command
yum clean dbcache
If still issue persist,run below given command
yum clean all
As per man page of yum :
yum clean dbcache
Eliminate the sqlite cache used for faster access to metadata. Using this option will force yum to download the sqlite metadata the next time it is run, or recreate the sqlite metadata if using an older repo
Given below is the reference from our system:
