Wordpress FTP Permissions Error

Evening all,
I am trying to set up my WordPress installation to automatically update as and when required.
So I have added my FTP account details to the WP_Config.php and then tried to update.
When I do this I get the below error but when I log in with the FTP account and create directories it works fine, Any ideas on how to resolve it?

Code:

define( 'FS_METHOD', 'ftpext' );
define( 'FTP_BASE', '/var/www/clients/client1/web1/web' );
define( 'FTP_CONTENT_DIR', '/var/www/clients/client1/web1/web/wp-content' );
define( 'FTP_PLUGIN_DIR ', '/var/www/clients/client1/web1/web/wp-content/plugins' );
define( 'FTP_PUBKEY', '/etc/ssh/ssh_host_rsa_key.pub' );
define( 'FTP_PRIKEY', '/etc/ssh/ssh_host_rsa_key' );
define( 'FTP_USER', '**********' );
define( 'FTP_PASS', '**********' );
define( 'FTP_HOST', 'localhost' );
define( 'FTP_SSL', true );

 

Hey Th0m,
Not sure what you mean by "Why use FTP instead of local editting?" it seems on Wordpress to use the auto update features you need to configure FTP access settings.
But yeah the ownership of the folders is correct.

 

Sure, I've included the snapshot below.
If I comment out the below script in WP-Config.php and then try an update I am prompted to enter the details for my FTP account which when I do and click on proceed the updates work fine, So maybe an issue with the script below? (Already tried commenting out the PUBKey and Prikey along with the SSL)

Code:

define( 'FS_METHOD', 'ftpext' );
define( 'FTP_BASE', '/var/www/clients/client1/web1/web' );
define( 'FTP_CONTENT_DIR', '/var/www/clients/client1/web1/web/wp-content' );
define( 'FTP_PLUGIN_DIR ', '/var/www/clients/client1/web1/web/wp-content/plugins' );
define( 'FTP_PUBKEY', '/etc/ssh/ssh_host_rsa_key.pub' );
define( 'FTP_PRIKEY', '/etc/ssh/ssh_host_rsa_key' );
define( 'FTP_USER', '**********' );
define( 'FTP_PASS', '**********' );
define( 'FTP_HOST', 'localhost' );
define( 'FTP_SSL', true );

 

Thanks Till, That now works perfectly.
