I started my Blogging career with WordPress using my localhost using LAMPP on my Ubuntu Laptop.
Also on localhost you come once in a while to a point where you need or want to update or upgrade your theme, plugins or WordPress 😉
It took me hours to come to the point to realize that I do not need a FTP-Server on my machine. Now that I know the solution, it looks not only really easy – it IS really easy!
You can do directly-“ftp” by add a single setting within the wp-config.php file.
All you need on to is to ensure WordPress can write to your local /www/ directory;-)
