Description Patricia Moeller 2017-04-10 10:36:32 UTC 
Description of problem:
I am trying to run puppet 4.6.2-2 standalone in a F26 alpha chroot environment but always got the following error message:

Comment 1 Dominic Cleal 2017-04-10 11:19:13 UTC 
This looks like an incompatibility of the Puppet monkey patch with Ruby 2.4 when using OpenSSL 1.1.0 or higher.

Ruby 2.4 only sets a default ciphers list of its own on OpenSSL versions older than 1.1 (https://github.com/ruby/ruby/commit/c9dc016#diff-8406e11e4a42f9de6badcd0f6a6c4262R33), so this monkey patch is trying to modify an array that's no longer present.

The Ruby OpenSSL commit (https://github.com/ruby/openssl/commit/b9aea27) that removed it suggest the cipher list in 1.1.0 is secure enough by default, and the list in the commit doesn't list any SSLv2 ciphers, which is what Puppet's trying to disable.

I think the monkey patch could be removed or made conditional in Puppet in Fedora 26+, which uses OpenSSL 1.1.0.
Comment 2 Patricia Moeller 2017-04-10 11:23:25 UTC 
Thanks for pointing that out. Sounds like a good idea to me. I just want to confirm that it not only occurs in chroot but also when simply trying to execute it on a F26 box.
