Why is the xdebug tutorial asking to use the automake command and how to fix the error?

Question

PHP

[email protected]:~/Downloads$ sudo apt-get install php-dev autoconf

The newest autoconf package is already installed ( 2.69-11).
The latest php-dev package (2:7.4+75+ubuntu18.04.1+deb.sury.org+1) is already installed.
0 packages updated, 0 new packages installed, 0 packages marked for removal, and 1 packages not updated.
[email protected]:~/Downloads$ automake
automake: error: 'configure.ac' is required

PS The packages were not installed, just closed the terminal after installation, then, purely for the forum, entered the commands again
. Of course, there are questions about the error on the forums

automake: error: 'configure.ac' is required

but not in this case. So what to do?

Answer 1

sudo apt-get install php-dev autoconf automakeis one line, not two.
> So what to do?
install automake:
sudo apt-get install automake
