After upgrading an ASR9000 router from 4.2.0 to any higher version, the install verify failed with the following errors: (In this case higher version is 4.2.1) Info: /install/asr9k-base-4.2.1: [ERROR] Detected anomalies.

It is also seen after upgrade from 4.2.0 to any higher version and a redundancy switchover is performed. Try to compare syslog after switchover with following logs: RP/0/RSP0/CPU0:ASR-PE7#sh log | i %INSTALL-INSTREPL-7-FILE_OPEN_FAILED Wed Jul 11 14:17:25.271 UTC RP/0/RSP0/CPU0:Jun 14 16:28:13.257 : sw_dwnld_svr[410]: %INSTALL-INSTREPL-7-FILE_OPEN_FAILED : Failed to open file '/disk0/asr9k-base-4.2.1/0x100401/lib/libether_ctrl_mgmt_netio.dll' while creating a file stream: No such file or directory.

Perform upgrade from 4.2.0 to higher version using the mandatory SMUs on 4.2.0, and then perform a install verify. On a system with Dual RSP there is no functional impact. On a system with a single RSP, the system will still work as expected, but if a new RSP is placed in the system it will not completely sync all the packages, and it will not come up as standby ready. At that stage a turboboot is required.
Turboboot the desired higher version ONLY if the system is running with a single RSP, else no action is required on a dual RSP system, the output of install verify can be ignored.
