I am trying to upgrade the firmware using the file cmterm-78xx.14-1-1-0001-136.k4.cop.sha512. When I try to upload the file I get the following error:
"Error encountered: The selected file is not valid. Please ensure that the COP/ISO file is intended for this release. MD5 Hash Value: 2a:ed:a9:25:1e:0b:21:94:78:9a:47:02:23:56:42:87"
I see that they have changed the security using a new hash algorithm and not sure if I need to install a patch on my CUCM in order to get this working. I am running CUCM version 12.5.
Solved! Go to Solution.

So I was able to find out that it looks like I need to apply the following package
ciscocm.enable-sha512sum-2021-signing-key-v1.0.cop.sgn
I will do that and see if it resolves my issue.

You need to install the COP ciscocm.enable-sha512sum-2021-signing-key-v1.0.cop.sgn if you are below versions to enbale sha512 signed files.
