blowfish_secret ERROR with phpmyadmin

With the latest version of ee stack install --phpmyadmin

Received following error after logging: “ERROR: The configuration file now needs a secret passphrase (blowfish_secret)”

Another warning is: “The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. To find out why…”

But issue: #301 said this should be fixed

Did I miss any thing here?

Another thing worth to mention that, “ee stack install --utils” does not install phpmyadmin, although the documentation said it should do
