The following error messages occurred when applying CP-OS-140300-Latest.tar.gpg on Virtual Appliance (vApp).
[ERROR] No applicable RPMs were found
[ERROR] The CP installation failed with error #16
[ERROR] CP-OS-140300-Latest.tar.gpg - error code 16
Release : 14.3
Component : CA IDENTITY SUITE (VIRTUAL APPLIANCE)
The errors are benign. Looking at ca_vapp_main.log file the following is shown

This error happened if at 14.2 level the latest CP-OS-14.2.0-20200416 patch has already been applied. The vApp platform is based on CentOS 6 and there is no latest OS patch than CP-OS-14.2.0-20200416 patch for this OS. When vApp is upgraded to 14.3 and CP-OS-140300-Latest patch was applied, it errors out because there are no applicable RPMs to be applied.
Those error messages are benign and you don't need to take action.
To confirm, run the following command on the vApp node and compare the result with vApp node where CP-OS-140300-Latest patch is applied.
rpm -qa | grep kernel
It should yield the same kernel version.
