With Sagemath version 6.6 the command "sage -notebook = ipython" worked fine.

I upgraded to the 6.8 version and every time I try the same command, I get the following message:

The IPython notebook requires ssl, even if you do not use https. Install the openssl development packages in your system and then rebuild Python (sage -f python).

Does anyone know the correct way workaround this?

This might depend on the OS you use. What operating system are you using?

Eg. if you are using Debian based OS (eg *buntu) you may try installing libssl-dev, or if you are using a Red Hat based OS you can try openssl-devel.

Got the same problem here. The problem is that the version installed by ubuntu is libssl-dev (with libssl version 1.0.0) and Ipython wants a more recent one.

One solution is to install openssl Sage package with

$ sage -p openssl

Then it should work
