NTOPNG in NethServer 7.8 Error

Hi, I’m sorry if I have filed this under a wrong category but I think it’s a bug because NTOPNG Application was working before I upgraded to NethServer 7.8. Now the application shows this error:

Script “/usr/share/ntopng/scripts/lua/index.lua” returned an error:
/usr/share/ntopng/scripts/lua/modules/plugins_utils.lua:33: attempt to call field ‘getCurrentPluginsDir’ (a nil value)

Log file shows this:

I’m sorry if this is just a little tinkering but I’m a non IT guy implementing IT stuff. Can anyone show how to resolve this. Thank you very much for any help.

Hello @willy06!

This is an upstream problem we faced on some installations.
I know that @davide_marini fixed it by removing and reinstalling some packages.

Davide, could you please share here your solution? :wink:

hello @willy06, I solved the problem by completely removing ntopng and his dependencies.
In fact the solution is quite simple, just paste this command in the shell:

yum remove pfring

This will remove pfring, ntopng and nethserver-ntopng , so it should be safe.
After that just go to the software center and newly install ntopng.
I did this 4 or 5 times so far, always it solved the problem without any drawback.

Thanks for the tip. I did find a thread somewhere that says it’s a bug and to wait it out for the next release. I also tried to remove the Bandwidth Monitor application then reinstalled it but still the same error. I’ll try removing pfring later. Hopefully it’ll work.

please verify first to reinstall ntopng that you don’t have installed pfring-dkms, in this case remove it before the new installation.
Let us know if it worked!

@davide_marini I missed checking the pfring-dkms and proceeded to removing pfring and reinstalled Bandwidth Monitor. Worked like a charm. Thank you very much for the kind assistance. Hail the NethServer Community.
