That's rather old, but wait before upgrading. I'm not sure the "time"
issue is solved in the latest version.

No, you have to install it on the *snapshot* used for creating the
worker machines. It's not there - I checked yesterday evening.

Did you reinstall GC3Pie or switch to a different Python virtual environment?

I suspect that the worker VMs might have some restrictions on the kind
of SSH key that can be used for login (e.g. Ubuntu 16.04 won't accept
DSA keys). You can print out the SSH key type with::
ssh-keygen -B -f $HOME/.ssh/cloud_jw
