mtr-paquet: Failure to open IPv4 sockets: Operation not permitted

Since I have upgraded my system from 18.04 to 18.10, I was unable to use mtr without root privilege.

$ mtr 9.9.9.9
Failure to open IPv4 sockets: Operation not permitted
Failure to open IPv6 sockets: Operation not permitted
mtr: Failure to start mtr-packet: Invalid argument

With sudo, everything work great.
