Luca, Thanks for the response. I reinstalled from the beginning.
However, I had to use Stretch not Jessie because RPI has moved on from Jessie as its default. I got to the last step in the instructions on http://packages.ntop.org/RaspberryPI/ (hoping the Jessie install would be ok) but got the following which I think means I need a Stretch specific build. Any chance you could do one? Charles root@raspberrypi:/home/pi# apt-get install ntopng nprobe Reading package lists... Done Building dependency tree Reading state information... Done 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 required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: nprobe : Depends: libzmq3 but it is not installable Depends: libhiredis0.10 but it is not installable Recommends: ntopng-data but it is not going to be installed ntopng : Depends: librrd4 but it is not installable Depends: libzmq3 but it is not installable Depends: libssl1.0.0 but it is not installable Depends: libhiredis0.10 but it is not installable Depends: libmysqlclient18 but it is not installable Recommends: ntopng-data but it is not going to be installed E: Unable to correct problems, you have held broken packages. <end> ======= Hi Charles packages have been just rebuilt. You do not need nProbe. In order to start ntopng you need to be root.
