Some OS X Server users attempting to upgrade to version 2.2 released last week are encountering difficulties in installing the new version whose flagship addition is a “caching” feature that speeds up downloads released by Apple through Mac App Store.
Apple acknowledges in a Support document released this week that customers upgrading to OS X Server app v2.2 from a previous version may see an alert stating, “An SSL error has occurred and a secure connection to the server cannot be made.”
“If this occurs you will be unable to finish setting up your server,” Apple says. Users must locate and delete the ‘com.apple.servermgrd’ identity preference and certificate. The computer mammoth says, “This will allow you to finish setting up your server.”
The simplest approach involves executing these two commands as an admin user:
sudo security set-identity-preference -n -s com.apple.servermgrd /Library/Keychains/System.keychain
sudo security delete-certificate -c com.apple.servermgrd /Library/Keychains/System.keychain
