My /etc/resolv.conf contains some old entries that I think broke my DNS.
It’s interesting that the nm-tray does not show the bad IPs.
What would cause the operation not permitted?
I booted off USB and my nvme file systems have no errors.
It is ext4fs.
$ ls -l /etc/resolv.conf
-rw-r--r-- 1 root root 50 Feb 9 2022 /etc/resolv.conf
$ sudo rm /etc/resolv.conf
rm: cannot remove '/etc/resolv.conf': Operation not permitted
$ sudo -s
# chmod a+w /etc/resolv.conf
chmod: changing permissions of '/etc/resolv.conf': Operation not permitted
