dpkg error: " dpkg: error processing package ice-zc-dkms (--configure):

[utkarsh0902311047]

Hi,
Since last week I am trying to update and upgrade Ubuntu 20.04 and I keep getting errors for dpkg.
I have attached the snapshot of the errors.

Please help

[cardigliano]

@utkarsh0902311047 are you running Ubuntu server LTS with the default kernel? I see you are running kernel 5.11, it should be 5.8 (this is what Ubuntu 20 is running in our lab)

[utkarsh0902311047]

I am using Ubuntu Desktop 20.04.2 LTS
So it won't work on Kernel 5.11?
Which kernel should I install from the image attached?

[cardigliano]

I suggest to install 5.8 which is what is supposed to run on Ubuntu 20

[utkarsh0902311047]

I have now set kernel 5.8 but still get the same errors.

[cardigliano]

Could you provide one of the generated log files? (e.g. /var/lib/dkms/ixgbe-zc/5.5.3.6804/build/make.log)

[utkarsh0902311047]

Here it is
make.log

[utkarsh0902311047]

Please give any suggestions what should I try?

[cardigliano]

It seems to be due to the kernel version, you are running a 5.8.0-050800-generic, the Ubuntu kernel version should look like 5.8.0-48-generic

[utkarsh0902311047]

Ok now when I set the kernel to 5.8.0-63-generic, it gets updated properly. Thank you for helping with updating.
Now when I use the pf_ringcfg --configure-driver ice --rss-queues 4, cat /proc/net/pf_ring/dev/ens5f1/info shows zc driver but TX and RX queues still show 1. They should show 4 right?

[cardigliano]

What pf_ring version are you using?
Please provide cat /etc/pf_ring/zc/ice/ice.conf
Please try with a reboot to make sure pf_ring is reloaded.

[utkarsh0902311047]

PF_RING version 8.1.0. It automatically gets updated to 8.1.0 when I run apt-get update && apt-get upgrade

[cardigliano]

Please try with a reboot to make sure pf_ring is reloaded.
After that please provide cat /proc/net/pf_ring/dev/ens5f1/info again.

[utkarsh0902311047]

After reboot this is the output of the command cat /proc/net/pf_ring/dev/ens5f1/info

[cardigliano]

The ice driver is not getting loaded, it looks like a misconfiguration, please provide:

tree /etc/pf_ring
cat /proc/net/pf_ring/info

[utkarsh0902311047]

here it is

[cardigliano]

Uhm you said "updated to 8.1.0", but 8.0.0 is loaded, please cleanup the environment

[cardigliano]

and make sure ice-zc-dkms is installed

[utkarsh0902311047]

Uhm you said "updated to 8.1.0", but 8.0.0 is loaded, please cleanup the environment

First I was trying with development builds which installs pfring 8.1.0
Since it was not giving satisfactory results I tried stable build.

Yes, this command I have already executed "apt-get install pfring-drivers-zc-dkms ".
Should I install development builds?

[cardigliano]

Please do a "systemctl restart pf_ring" and provide me the output of "systemctl status pf_ring"

[utkarsh0902311047]

It seems ice-zc driver not installed properly. But there was no error while installing. What should I do about it?

[cardigliano]

Please make sure the ice-zc-dkms package is installed.

apt-get update
apt-get install ice-zc-dkms

[utkarsh0902311047]

I update and then apt-get install ice-zc-dkms says E: Unable to locate package ice-zc-dkms

[cardigliano]

@utkarsh0902311047 it seems there is some misconfiguration, the ixe-zc-dkms package is actually available for Ubuntu 20 as you can see at https://packages.ntop.org/apt/20.04/all/ (it is working for me). Please try reconfiguring the repository.

[utkarsh0902311047]

When I run this command "apt install ./apt-ntop.deb", I get the following message in the end. Should I ignore it?
N: Download is performed unsandboxed as root as file '/root/apt-ntop.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)

[utkarsh0902311047]

I have again download the repository from development build. The pf_ring version is now 7.9.0. The ice driver is installed.
But the queues it shows is still 1.
I have attached a snapshot of the commands
cat /proc/net/pf_ring/dev/ens5f1/info
cat /etc/pf_ring/zc/ice/ice.conf
cat /proc/net/pf_ring/info

[cardigliano]

@utkarsh0902311047 please note the pf_ring version in the dev/nightly build repository is 8.1, this means there is some misconfiguration. If you installed latest packages, it is likely the pf_ring module has not been reloaded (or it has not been reinstalled by dkms, or there is some old pf_ring.ko module installed). First of all I would try with a system reboot. If the problem is still there, I would try playing with the dkms command to rebuild the pf_ring module.

[utkarsh0902311047]

Ok done. Now what should I do to get the queues equal to 4?

[cardigliano]

Set RSS=4,4 in /etc/pf_ring/zc/ice/ice.conf, then restart the pfring service with systemctl restart pf_ring

[utkarsh0902311047]

I already tried that. But still it shows queues 1.

[cardigliano]

@utkarsh0902311047 are you still unable to set RSS? Could you provide ssh access?

[utkarsh0902311047]

Yes, I am still unable to set the TX and RX queues 4.
I have injured my leg so I am not able to go to the lab this week.
Is it possible to give you ssh access next week?

[cardigliano]

Sure, feel free to come back on this as soon as you recover from the injury. Drop an email to cardigliano at ntop.org with the credentials.
