This is the error message I receive on my Arch Linux based system:
os-release:
uname -a
pacman -Qs netfilter
ls -lah $(which iptables)
Excerpt of `dmesg -wH` while portmaster starts up (contains a nmcli segfault, but nothing else afaik) (use arrow to expand)

This is on my Manjaro Linux based system: uname -a
pacman -Qs netfilter

This is an excerpt of `dmesg -wH` when starting the portmaster service (BUG log in there!) (use arrow to expand)

👋 @ppacher, investigate . |
Hi @markusressel, Thanks for your help! For your pure arch-system:
Is it possible that you did an system (kernel) upgrade but didn't reboot? That could explain why the table does not exist. For your Manjaro system: I stumbled across a similar issue that has been reported to gustavo-iniguez-goya/opensnitch#41. Seems like this is a kernel/netfilter issue. I'm running two systems with kernel 5.7.7 and libnetfilter_queue 1.0.5-1 without any issue. Could you try updating Manjaro? I'll keep trying to reproduce this and will keep you updated. |
I'm able to reproduce the kernel panic even on a 5.7.7 when using the slub_debug=FZP commandline parameter. @gustavo-iniguez-goya already created a netfilter bugreport for that. Can you check you kernel command line and see if that option is used in Manjaro? |
At the time of reporting I thought about that too, so I did restart several times, but nothing changed. However, I tried to start it again today and it works as expected 🤔 . I have updated the system several times in between, so I do not exactly know what caused this, when it caused it or why. Portmaster version is now
I just tried to start portmaster again with only system updates, but nothing changed. I will try to update to kernel |
This is the output of

Updating Manjaro to kernel version |
@markusressel good to hear it's now working for you! Thanks for your support in debugging this! For reference: patch. |
Hi, Just wanted to let you know that I've got the same problem here, on Ubuntu 20.04 LTS with kernel 5.4.0-91-generic. It's badly freeze after install, and the reboot show a black screen during few minutes, and after logging the desktop apears with this error after few minutes. For me it's not a great user XP on ubuntu so I've unistalled it - you should drop ubuntu support or handle this with a fallback. |
