After my previous topic, I have a new error:

This is what I did, before getting the error:

sudo mkdir -p /etc/systemd/system/incus.service.d
sudo vim /etc/systemd/system/incus.service.d/override.conf # To add the content below
# [Service]
# Environment=INCUS_SECURITY_APPARMOR=0
sudo systemctl daemon-reload
sudo systemctl restart incus.service

incus network create incusbr0

I use Nobara Linux 42.

Is anything weird going on with /var/lib/incus such as there being some symlinks in that path?

3

I ran a sudo find /var/lib/incus/ -type l -ls, there is no symlink :confused:

4

What does readlink -f /var/lib/incus/networks/incusbr0/dnsmasq.raw get you?

5

Given apparmor is disabled, that’s probably unrelated, though then it’s pretty confusing as to why dnsmasq wouldn’t be able to access that path.

6

This is the output of readlink -f /var/lib/incus/networks/incusbr0/dnsmasq.raw command:

/var/lib/incus/networks/incusbr0/dnsmasq.raw
7

I try to reinstall Incus, and now there is no output when I run readlink -f /var/lib/incus/networks/incusbr0/dnsmasq.raw
