I've been attempting to figure this out for 5 hours now. Hopefully someone who is more knowledgeable, can help me out.
Randomly, without me making any changes to my device, my internet cut out. I tried to ping Google DNS, but was met with
sendmsg: operation not permitted. I spent hours Googling this issue, and tried every solution known to man, with no success. If anything, I broke it even further.
Here is some helpful data:
$ cat /etc/network/interfaces auto lo iface lo inet loopback allow-hotplug wlp3s0 iface wlp3s0 inet dhcp
$ cat /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile,afono [ifupdown] managed=true
$ cat /etc/systemd/resolved.conf [Resolve] DNS=126.96.36.199 DNSStubListener=no
/etc/dhcpclient-enter-hooks.d/samba returned non-zero exit status 1 ... send_packet: Operation not permitted ... dhclient.c: Failed to send 300 byte long packet over fallback interface
$ ping 188.8.131.52 ping: sendmsg: Operation not permitted
$ ping [broadcast IP] -b ping: sendmsg: Operation not permitted
