Hi. I wanted to know if it's needed to install a firewall on a linux desktop/laptop. Why yes or why no?

    Yes, except that whether you do is not at all obvious.

    Do you use KDE Connect? If yes, you run a network service. Syncthing, a bittorrent client? Those too, and many others. I know this is a Linux community, but as a comparison windows has a bunch of network services running by default.
    By saying "network services", I think menu of us would just think about a web server or a file server, conclude that they don't run any of those, and don't bother with it.

    When in doubt, sudo netstat -lutpn, and look for the listening ports to see what software listens for informing requests.
