Hi Guillermo - so here are the actual log files and the .st I���m running with build.sh (its a normal pharo command line execution). Its running on Ubuntu 17.10,  with Pharo 6.1 64 bit.

I got Pharo like this:

VM_STRATEGY="vmI61";
curl http://get.pharo.org/64/$VM_STRATEGY | bash;
curl get.pharo.org/64/61 | bash;

The error at the top of the log is:
LGit_GIT_ERROR: SSL error: error:140E0197:SSL routines:SSL_shutdown:shutdown while in init
15 May 2018 3:01:38.976377 am

And a few lines down you see it has translated the github:// url (in the baseline package) to https but then it seems to fail��� although is that https translation correct? I have also tried specifying https repos in the baseline myself (but you can���t easily control the baselines it in turn refers to) but that didn���t work either.

I was successfully doing something like this months ago with PharoLambda - but I suspect if I rerun that pipeline it may also fail like this.
