So I'm trying to update CER from 22.214.171.12400-28 to 126.96.36.19900-37going through the GUI as I'm not to knowledgeable or comfortable doing said upgrade from CLI. I keep running into the same issue at the same spot. Once I select the Software Upgrades/"install/upgrade" and input the remote filesystem and select next it pulls up the list of available and correct files. I try to run "ciscom.cer_preUpgradeCheck-3.k4.cop.sha512" or the update "UCSInstall_CER_188.8.131.5200-37.sha512.ISO" it attempts to download and then give me a status of Error encountered: The file or directory could not be located. witch is odd as the file server was showing it just fine. this is occurring on both PRI and SEC servers. I have opened a TAC case with not much help. I have updated CUCM cluster to 14 this last Sunday if that makes any difference. I have done multiple restarts and verified that the server has plenty of disk space. The only thing I think it might be but have no supporting information on my thoughts. But that there is currently an inactive version already loaded, this is an older version. Any ideas or help would be great on points to start from.
Tip to fix if CER Update Fail-
