Many problems on this website create the appearance that something is missing from Ubuntu and that a remedy might involve
sudo apt install. Unfortunately many posted solutions do not have references. For example is the following.
askubuntu has a web page for the following problem.
Gtk-Message: Failed to load module "canberra-gtk-module"
The answer with the most up-votes has 389 up-votes. askubuntu.com link
The solution with the most up-votes does not seek to install using the same string that is cited in the error message. In other words the answer is not
sudo apt install canberra-gtk-module. The solution with the most up-votes is somewhat similar to that but not exactly. Since it is not exactly that, ideally the correct answer or the most up-voted answer should have a reference to a canonical source.
How can I independently verify via referencing canonical sources that the most up-voted answer is the correct answer?
aptwhile others prefer
apt-get. Welcome to the maze of linux uniformity. As time progressed, and gtk3 became prevalent,
canberra-gtk3-modulebecame available, whereas
apt-getis not the only difference.
aptwas introduced in Ubuntu 16.04. itsfoss.com/apt-vs-apt-get-difference
apt-getis still useful for the vast majority of users so I always use
apt-getwhen I started with Ubuntu, and apt was added later. There was no shift, as
apt-getis still as useful as before, so why change.
aptand I also use
aptso the difference does not arise from the installation program. This question is about the package names.
