I've just tried to install freeradius on Ubuntu 16.04.4 LTS and no conf files are installed. I performed an apt-get update and apt-get upgrade before the install. :/# find /etc/freeradius/ /etc/freeradius/ /etc/freeradius/certs /etc/freeradius/sites-enabled /etc/freeradius/sites-available /etc/freeradius/modules /etc/freeradius/sql /etc/freeradius/sql/mysql :/# I've tried two different Ubuntu 16.04.4 LTS servers and both have the same problem. I've tried removing, force reinstalling, and having no luck.
