Operation not permitted

  • Main question:

    Why we got ” Warning: chmod(): Operation not permitted in /var/www/www.website.kanat.co.il/wp-admin/includes/lass-wp-filesystem-direct.php on line 173″ when trying to made update plugins in WP admin panel? (PNG attached “line 173…..” with code strings).

    We make update with role administrator (login:kanat), on linux we have users: apache and kanat. Owner of most folders and files – apache.

    Pls help us to resolve error on line 173.

    Additional questions:

    All site files permissions 674, but on official site WP wrote that it must be 644. Is it correct ? (PNG attached “file-674…..”)

    All folders have 775 permissions, , but on official site WP wrote that it must be 755. Is it correct ? (PNG attached “folder-775…..”)

    All files and folders have ACL, is it correct to delete them (ACLs) and make by default?(PNG attached which ACL we have now) Want to make like that, for folder:

    user::rwx

    group::rwx

    other::r-x

    and

    user::rw-

    group::r–

    other::r—

    is it correct to make that’s permissions ?

    Something isn’t right with file/folder ownership and/or permissions for chmod to be not permitted. Likely is the folder in question isn’t owned by the system user that PHP and WP are running under.

    755/644 are typical permissions, in some installations group permissions (2nd number) may need to be elevated. 775/664 are not unheard of. 674 is a little strange, unless the file is system executable that’s required for something. It wouldn’t impact non-executable files anyway. Also, why allow group execution but not owner? It’s odd but it wouldn’t impact chmod.

    The presence of ACLs tells me you have a complicated permissions scheme. If all permissions are correct without them, you shouldn’t need them. But if they are there they must have been needed for some reason?
