I not 100% sure that the Freedombox install is broken ? but it a lot better when these LDAP config options are avoided !
Like when using the command line and sudo DEBIAN_FRONTEND=noninteractive apt-get install freedombox. You are not given options that could brake the install of Freedombox.
I do think that it does not matter how these questions are answered. FreedomBox will completely and properly reconfigure the packages involved. I have tested with providing default answers to these questions and everything seems to work. This is the same as when people simply run ‘apt-get install freedombox’ without the DEBIAN_FRONTEND=noninteractive part. Please confirm if are seeing issues here. We would like to fix those too separately.
