Conditions

Workaround

IF we add the mentioned file in the logs, it works in the above example it was "C9800-SW-iosxe-wlc.17.09.01.SPA.bin" Sometimes it will expect previous smu files and subpkgs to be present in the flash

Further Problem Description

If an image installed a SMU or wireless subpkg in the past, then installs different base image, then removes the SMU or wireless subpkg, the install of a different SMU will cause this issue. The patch.sta files will retain the previous history of the SMU/subpkg installs - this is both for rollback history, and also so that if the base image is ever re-installed, the SMU/subpkg will automatically apply.
