I'm getting the following error in CUCM when attempting to edit a device after we updated from 11.x to 12.x
Update failed. SSH Password is not valid. SSH Password is an encrypted value containing up to 288 hexadecimal characters (0-9 and A-F)
I'm still digging around but I feel like a feature/service was enabled by default after the upgrade that I need to locate and disable?
Are you able to change the "Secure Shell Password" on the Device -> Phone Page?
