Install wordpress plugin on the local machine

I am making a site in wordpress, the problem is that as I am new I am testing everything on my local machine, for this I configured apache and installed wordpress.

In /etc/hosts file I configured my wordpress with the following Route:

127.0.0.1       question.com.br question

My problem is that now I want to install my first plugin and I came across the screen where it asks me for the Hostname, and I have no idea what it is.

Can anyone me help?

Update

Improved my situation a bit by adding the line

define('FS_METHOD', 'direct');

But he started installing but gave the following error on output:

Downloading install package from https://downloads.wordpress.org/plugin/profile-builder.2.3.1.zip…

Unpacking the package…

Could not create directory.

Is there a permission issue in the folder?

I've tried the following commands in my folder but they didn't work:

maquinha@maquinha-desktop-1 /usr/share $ sudo chown -R www-data:www-data wordpress/
maquinha@maquinha-desktop-1 /usr/share $ sudo chmod -R g+rw wordpress/

This is my exit from permissions for command ls -l
