Cannot install ixgbe zero copy drivers

[DerRealKeyser]

When attempting to configure ixgbe zero copy drivers on Ubuntu 22.04.3 with latest Ntop 6.0 stable (ntopng Enterprise L v.6.0.240110 rev.22572 (Ubuntu 22.04.3 LTS) ) the drivers refuse to install with a dependency error on pfring-dkms: A full apt-get upgrade has completed just before the attempt, and everything is updated.

This should've been addressed, please try with apt clean all, update, upgrade

Hmmm, then I get an update showing some updates have been held back - including ntopng and ntopng-data. If I try to include those in the upgrade with --with-new-pkgs I get a:

So it seems I have a "to new" pfring installed or? How do I resolve that? I'm not too experienced in the world of Linux.

Seems the never pfring and dependencies comes from the Ubuntu distribution and was installed earlier on an apt upgrade. How is it that repo has a newer pfring than what your stable build on Ntopng has/uses? Shouldn't a dependency of the installed ntopng has prevented it from upgrading pfring?

Seems its because the current installed NtopNG package (a week old) requires a newer pfring than the latest NtopNG:

It looks like this was caused by a broken ntopng package, I suggest to remove that package and start over

[DerRealKeyser]

A complete removal of Ntopng and a autoremove of dependent packages solved the issue.
