SX10/SX20/SX30 7.3.2 for CUCM image is not valid

[hxmengmetro]

Guys,

Not sure you noticed or not, the file in cisco website for CUCM image of SX10/20/80 has "k3" in the name, when I load it to CUCM, CUCM complained about it's not valid image. Do you have that problem too? I'm sure the image is good, I downloaded twice and checksum is correct. I noticed this 7.3.2 has "k3" in the name compared to 7.3.1.

Thoughts?

Hi Lou,

Quoted from TC7 release notes:

From TC7.3.2, all cop files for CUCM are signed with RSA3

To improve software integrity protection, new public keys are used to sign cop files for Cisco Unified Communications Manager Release 10.0.1 and later. To install a TC7.3.2 and beyond, cop file on a pre-10.0.1 Cisco Unified Communications Manager, consult the README for the ciscocm.version3keys.cop.sgn to determine if this additional cop file must first be installed on your specific Cisco Unified Communications Manager version. If these keys are not present and are required, you will see the error “The selected file is not valid” when you try to install the software package. The cop file names has changed, please see the below example:
cmterm-s52000tc7_3_2.k3.cop.sgn

Hi

If you downloaded these images more than 24 hours ago you might have got some corrupted images. This issue was resolved 24 hours ago, and you can simply download the cop file again. If this does not apply for you, please refer to the post by thobonho2.
