log is filled with firewall / netlink errors

[jerkstorecaller]

Ubuntu 22.04 amd64 using opensnitch 1.6.0rc1 with default configuration (except for allowing every popup I got). I did not touch the firewall configuration.

The following lines are written to /var/log/opensnitch.log every ~15 seconds:

[2022-07-02 11:53:18]  WAR  nfables filter rules not loaded: 1
[2022-07-02 11:53:18]  IMP  nftables firewall rules changed, reloading
[2022-07-02 11:53:19]  WAR  nftables: error applying changes: Receive: netlink receive: no such file or directory

Hi @jerkstorecaller ,

Did you change the firewall options/rules from the GUI? or the file /etc/opensnitchd/system-fw.json?

Enable please DEBUG logs and post the log file opensnitchd.log to see if there's any clue about the error.

Also post your ruleset : $ sudo nft list ruleset > ruleset.txt
