Hi, I tried executing the rpm -V command on the packages of the CentOS 7.2 ISO which I have created, the verification failed for some of them. Here is the log for 'authconfig' : Steps: 1. Execute command : rpm -V authconfig 2. Observe the output Expected Result: If there is no error, nothing should be displayed Actual Result: Verification fails with following error log: S.5....T.c /etc/sysconfig/authconfig -When I uninstalled the package and re-installed it using YUM, the verification for the same passed.- -When I executed the same command on the same package of CentOS-7-x86_64-Everything-1511.iso the verification failed. So, I concluded that the problem is not with my ISO as the same is failing for standard ISO also. Please provide info on what this -V option actually does, and why these verification is failing for even the standard rpms. Is that a flaw ???? Regards, Shagun
