 I want to build a Stack project on this system, but I receive an
 "impossible" error even when I try to build a trivial project.

 Downloading template "new-template" to create project "stacktest" in

The following parameters were needed by the template but not provided:
 author-email, author-name, category, copyright, github-username
 You can provide them in /home/users/ksb/.stack/config.yaml, like this:
 templates:
   params:
     author-email: value
     author-name: value
     category: value
     copyright: value
     github-username: value
 Or you can pass each one as parameters like this:
 stack new stacktest new-template -p "author-email:value" -p "author-
 name:value" -p "category:value" -p "copyright:value" -p "github-
 username:value"
