double upgrade messages in ssh welcome

I'm receiving double upgrade messages when logging into my Ubuntu cluster. Been happening for the last few months I think. Only the first one is real. I've done the second one, but the message continues to show up, along with the double "Welcome to Ubuntu!" message.

Any ideas for fixing this?

Thanks,

Frank
