Using GNU/Linux at all is. Choosing to use such an operating system and then also choosing to do your updates from a terminal emulator is even further off the beaten path.

The beaten path is the defaults. Windows and MacOS particularly.

And system updates don't need sudo on desktops, it is not 1990's anymore... GUI apps like software-properties-gtk use dbus with polkit auth to upgrade software without any involvement of "sudo" or giving root access to users.
