Text editors to investigate -
         Lime may be dead. I dunno. TBD
         I would consider using this on one of my LAMP servers.

How to Solve WordPress Could Not Create Directory
/08 Useful Tips /How to Solve WordPress Could Not Create Directory

I was having a "Installation failed: Could not create directory" problem for a long time.
Now that I've had some time to investigate and drill down into what the problem was, I have found a solution.

Applying "Web Server Ownership" and "Directory Permissions" as listed below worked for me. Quick and simple.

I used these chown and chmod commands to fix most all issues regarding installing "Themes" and "plugins":

1. Web Server Ownership
The first level is actually to make sure that your web server has ownership over the directories:
chown -R www-data:www-data your-wordpress-directory

2. Directory Permissions
The second level is also required – you must make sure that the directory permissions are properly set:
sudo find /var/www/wordpress/ -type d -exec chmod 755 {} \;
sudo find /var/www/wordpress/ -type f -exec chmod 644 {} \;
