An attempting update of ntopng on ubuntu 16.04 LTS resulted in this annoying error during 'apt-get install ntopng' ( run as root )

Executing /lib/systemd/systemd-sysv-install enable ntopng Failed to execute operation: File Exists dpkg: error processing package ntopng (--configure): subprocess installed post-installation script returned error exit status 1

I'd previously completely removed ntopng using commands - apt-get purge --auto-remove ntopng deleting any other files/directories in /etc that were left over such as the empty directories /etc/ntop, /etc/pfring, /etc/nprobe, /etc/cento and /etc/nbox. performed a reboot 'shutdown -r now' and checked no ntopng files were left hanging around using 'dpkg -L ntopng'.

So all looked OK for a complete reinstall but this error fails the new installation. Anybody have any idea what file the error is referring to ?

UPDATE - digging around, I had libfakeroot file left over in /usr/lib/x86_64-linux-gnu/libfakeroot which I trashed and started again - with same result.

  • have you tried apt-get install -f and then installing ntopng?

  • Just tried that after another complete deinstallation, clean up and reboot. I get the same error.

  • Try the following: rm -rf /var/lib/dpkg/info/ntopng* dpkg -P --force-all ntopng apt-get install -f apt-get install ntopng
