Details - The problem is that packages freeradius3-mod-eap-peap and freeradius3-mod-eap-ttls can't be installed at the same time. For example, if freeradius3-mod-eap-peap is installed first, then you get an error message for freeradius3-mod-eap-ttls:

check_data_file_clashes: Package freeradius3-mod-eap-ttls wants to install file /etc/freeradius3/sites-enabled/inner-tunnel But that file is already provided by package * freeradius3-mod-eap-peap
opkg_install_cmd: Cannot install package freeradius3-mod-eap-ttls.

As a result, the daemon doesn't work and the log reports this:
