grace@DESKTOP-PTDHEDF:~$ sudo traceroute -m3 8.8.8.8
traceroute to 8.8.8.8 (8.8.8.8), 3 hops max
1 * * *
2 * * *
3 * * *
Tried the following steps but the result still the same.
sudo apt-get install inetutils-traceroute
sudo apt install traceroute
sudo apt update
sudo apt upgrade
grace@DESKTOP-PTDHEDF:~$ sudo mtr 8.8.8.8
mtr-packet: Failure to open IPv4 sockets: Permission denied
mtr-packet: Failure to open IPv6 sockets: Permission denied
mtr: Failure to start mtr-packet: Invalid argument
mtr command is also not working
Any idea that what I still need to do?
Thank you.

do raw packet manipulation, you must run them as a privileged user, e.g.sudo mtr 8.8.8.8
. Readman sudo sudoers traceroute mtr
