Have you received the following dialog on your side?
If you have WordPress files and folders are not owned by your Apache you can try to eliminate the following dialog you need to write down this line:
# RH version chown -R apache wordpress-folder # Ubuntu version chown -R www-data wordpresss-folder
The same troubleshoot work when WordPress cannot write
wp-conf.php file during the installation.
This code will do even more:
chown -R www-data:www-data .; find . -type f -print0| xargs -0 chmod 644; find . -type d -print0| xargs -0 chmod 755
