I've recently updated my Ubuntu server from 14.04 to 16.04, but now I'm getting the error show below when I try & deploy using rocketeer, however it seems that the deployment continues and completed successfully despite these errors.

I've tried debugging, but it looks like the phpseclib packages does a load of binary string extraction form the SSH2 connections, and I have no idea where to start with debugging this.
Could it be to do with an updated version of openssl?
Here's the list of packages & versions it's using…

I'm happy to do more debugging if someone can please suggest how.
Any help is greatly appreciated.
For anyone coming across this ticket, I didn't manage to resolve the error messages, but as originally mentioned, the deployment completed fine, so for now I've not done any more investigative work.
