i have a fresh install of the latest raw version of check mk on a ubuntu 16.04.03 server. i do this to finish my education as IT specialist(system integration). On the first day, the graphs are shown at a few services, but at this time there are only red blocks with error messages of:
ERROR: STDERR = > /omd/sites/monitoring/bin/rrdtool: error while loading shared libaries: libpng16.so.16: cannot open shared objekt file: No such file or directory
I have tried to manually check the mistake, but i dont find any solution in the internet -.-
if i typ via putty "omd start monitoring"
It says, that all the services are running but one error occurs:
Starting rrdcached.../omd/sites/monitoring/bin/rrdcached: error while loading sh ared libraries: libpng16.so.16: cannot open shared object file: No such file or directory
I have updated the packages and reinstall libdbi-dev libdbi-perl but there is no effect. Same problem. Also i have thinked, okay restarting the server may helps by this problem, but computer says no and if i log in to check mk im getting errors while loading the dashboard. I have restored a snapshot, but i still know, if i restart the server the system is not able to work good.
Hope anyone can help me because this monitoring system is my finally project in my education :o
