I am new to all of this, so let me apologize if this questions has been already asked or if its solution is obvious: I have done some search and I have seen this question has been asked before (https://bitbucket.org/einsteintoolkit/tickets/issues/2069/connection-failures-to-svncactuscodeorg) but I cannot understand what should I do to fix it. I have never worked with SVN so I understand, basically, nothing. 

The problem is, when I try to download the ET, most of the packages install correctly, but some of them deliver this error:

I have tried installing again SVN, this is my current version: svn, version 1.11.1 (r1850623)

Also I am working on a MacBook (10.15.6), if that is of any help. I have no idea what to do to fix this. I would appreciate any help or guidance that you might provide. Thank you all in advance, I am so excited to join this community! 

Best, 

Jaime
