Hello, Now we used freeradius 2.2.5, but he is End-of-live,we will migrate to freeradius version 3. Because freeradius 3.0 absent in standart repository Debian 8, I downloaded Debian 9.2.1 with official site. After i tried install freeradius (apt-get update && apt-get install freeradius)and recieve error: "*Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some requred packages have not yet been created or been moved out to Incoming*" Instalation i did from standart repositiries. Two questions: 1) Can i install freeradius version 3 on Debian 8 using standard tool (apt-get or aptitude)? Maybe add new repository or only how as separate packet? 2) How i can install freeradius version 3 on Debian 9 using standard tool (apt-get, aptitude)? Maybe add new repository or only how as separate packet? With respect Yuri.
