I didn't receive an answer yet for an issue in GitHub which I created on Oct 20, 2017 so I'll ask here

Yesterday (Oct 19), 13.5.22 was the latest prerelease of chef-client.

I installed it using the following parameters during knife bootstrap

--bootstrap-version 13.5.22 --prerelease

However. today (Oct 20) when I wanted to bootstrap 13.5.22 using the same parameters, chef installed the chef-client 13.5.25.

Removing the --prerelease caused a download failure, it could not find v. 13.5.22 that way.

How can I still install 13.5.22 during bootstrap?

The original GitHub issue is this one:

Hi,

Knife bootstrap unfortunately needs a fairly major overhaul; some of that work is captured in [https://github.com/chef/chef/issues/3920](https://github.com/chef/chef/issues/3920) , and the move to `mixlib-install` would fix your problem.

I’ve not tried this but, try passing `--bootstrap-version "13.5.22 -c current"` to the bootstrap script. Otherwise, you can take a copy of [https://github.com/chef/chef/blob/master/lib/chef/knife/bootstrap/templates/chef-full.erb](https://github.com/chef/chef/blob/master/lib/chef/knife/bootstrap/templates/chef-full.erb) and add `-c current` to [https://github.com/chef/chef/blob/master/lib/chef/knife/bootstrap/templates/chef-full.erb#L174](https://github.com/chef/chef/blob/master/lib/chef/knife/bootstrap/templates/chef-full.erb#L174) . I know neither of these are ideal but they should get you going.  
Cheers,  
-Thom

Ok, thank you very much. I guess I’ll just wait for the issues to be fixed
