Actually, this did not solve the problem.
It seems that this error comes from openssh-client (when running `ssh`). After the update, openssh-client was no longer installed, and the default dropbear was mapped to "ssh".
My goal is to set up `sshtunnel`, which requires `openssh-client`. After re-installation of openssh-client, the error is back :(
My guess is that openssh-client must be built against the new version of libcrypto.
