Failed to generate PXELinux template: undefined method `template' for nil:NilClass

Having trouble with your foreman installation where machines aren't marked as "built"? You probably deleted the PXE Local Default file and now things silently crash. There's a bug report about it here.

When it happens you'll get a message like this in /var/log/foreman/production.log:

The solution is to create a template named "PXE Localboot Default". This is case sensitive so don't fat finger it! This template is applied to each host after the build process is complete.

By the way, the build process is completely when you're host sends this:

/usr/bin/wget --quiet --output-document=/dev/null --no-check-certificate <%= foreman_url %>
You can create the file from scratch. The default one usually works fine
