I would check the actual user/group used on the wp-content/plugins/akismet folder and any files inside of it to make sure they are what you expect them to be, as this is definitely a permissions issue.
If you can install plugins, I’d recommend installing the Health Check plugin, as it will allow you to perform some tests, and check the debug section to find out if it detects any access issues for directories commonly used by WordPress.
]]>I have Health check installed so the only mark is: Your installation of WordPress prompts for FTP credentials to perform updates. (Your site is performing updates over FTP due to file ownership. Talk to your hosting company.)
That’s correct WP aks for FTPS details and is working.
]]>// forces the filesystem method: “direct”, “ssh”, “ftpext”, or “ftpsockets”
define(‘FS_METHOD’, ‘ftpext’);
// hostname:port combo for your SSH/FTP server
define(‘FTP_HOST’, ‘domain’);
// either your FTP or SSH username
define(‘FTP_USER’, ‘domain’);
// password for FTP_USER username
define(‘FTP_PASS’, ‘password’);
NOW health is reporting (NO ERROR’s)
Your installation of WordPress doesn’t require FTP credentials to perform updates.
Still the problem is the same Installation failed: Could not copy file.
]]>>check both file/group ownership
Yes My FTP user wordpress can create read write del etc..
Yes My FTP user admin can create read write del etc..
>CHMOD settings on the afflicted files and directories?
CHMOD settings, is NEW for me can you explain more.
General I don’t know where the problem is.
01 Is Synology DS118 NAS the the problem
02 Is WordPress 4.9.6 the problem
CHMOD is also filepermissions, they are best explained by something like the wiki article at https://en.wikipedia.org/wiki/Chmod.
