TL;DR

Use the --remove flag, similar to how the PPA was added:

sudo add-apt-repository --remove ppa:whatever/ppa

...

You can also remove PPAs by deleting the .list files from /etc/apt/sources.list.d directory.

Last but not least, you can also disable or remove PPAs from the "Software Sources" section in Ubuntu Settings with a few clicks of your mouse (no terminal needed).

netstat

sudo netstat -tunlp

-t - Show TCP ports.
-u - Show UDP ports.
-n - Show numerical addresses instead of resolving hosts.
-l - Show only listening ports.
-p - Show the PID and name of the listener’s process. This information is shown only if you run the command as root or sudo user.

ss

sudo ss -tunlp

ss is new netstat. It lacks some of the netstat features but exposes more TCP states and it is slightly faster.

lsof

sudo lsof -nP -iTCP -sTCP:LISTEN
# or
sudo lsof -i tcp:80 -n -P

lsof is a powerful command-line utility that provides information about files opened by processes.

-n - Do not convert port numbers to port names.
-p - Do not resolve hostnames, show numerical addresses.
-iTCP -sTCP:LISTEN - Show only network files with TCP state LISTEN.
