Install wordpress plugin on local machine

Question

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

in the file /etc/hosts 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 he asks me the Hostname, and I have no idea which is.

Can someone help me?

UPDATE

improved a little my situation by adding the line

define('FS_METHOD', 'direct');

but it started to install but gave the following error in the output:

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

Unpacking the package…

Could not create directory.

is some permission issue in folder?

I have tried the following command in my folder but it did not 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 to command ls -l

Answer 1

you can download the plugins to unzip and put in the "wp-content/plugins/" folder, then just activate directly in the admin panel, or add the next line to wp-config.php

define('FS_METHOD', 'direct');

With this setting will also manage to upgrade to Wordpress by admin panel, without it when there is upgrade to Wordpress will appear the same form that is now appearing...
