you must use a certificate name that is currently installed - iOS signing app error

[pablo]

I am trying to update my iOS app to the latest version 1.5.0, and I keep getting this error when resigning it. Can anyone explain as to what it means ?

Thanks.

It means the security certificate isn't currently installed in your keychain. You should consult Apple's documentation and reinstall your certificate for signing.

thanks Wayne. In the end I had to use the full name with the app ID
i.e. iPhone Distribution: first name (K2LXXXXXX)
