Hi, 

I am trying to build a project in ubuntu 16.04.3. To this:
- I downloaded Pharo 6.1 (60541) 64bit
- I open the Pharo image and execute:

Metacello new
   baseline: 'GToolkit';
   repository: 'github://feenkcom/gtoolkit/src';
   load.
I have the following issue: LGit_GIT_ERROR: SSL error: error:140E0197:SSL routines:SSL_shutdown:shutdown while in init
The full stack is below. 
I can clone the repository from a terminal using: git clone git@github.com:feenkcom/gtoolkit.git
I believe that my settings are correct (same that I use on macOS): 



Is Iceberg suppose to work on Ubuntu 16.04.3 64bit?
I have noticed that it works in Pharo 7 64bit (excluding the fact gtoolkit does not work in Pharo 7 yet).
I found this bug report that might be related: https://github.com/libgit2/libgit2/issues/4644 

Thanks!
Juraj
