Hi Anthon,

we are not using any fqdn.
we’ ve already set the ip-address (Loopback-Adresse) in our configuration, as mentioned earlier:

define(‘FTP_HOST’,’127.0.0.1:22');

define(‘FTP_METHOD’,’ssh2');
define(‘FTP_PUBKEY’,’/xxx/xxx/xxx.xx’);
define(‘FTP_PRIKEY’,’/xxx/xxx/xxx.xx’);
define(‘FTP_USER’,’xxxxxxxx’);
define(‘FTP_PASS’,”);
define(‘FTP_HOST’,’127.0.0.1:22');

Well, i did use the ip-address from our host. Didn’t work. Same error as above. Starting with:

No worries.
Removing the Plugin didn’t work.

Hi,

thanks for helping us out. It's very appriciated.

CURRENT KONFIGURATION

+++++++++++++++++++++++++++++++++++++++++++++++++

We are running an sftp-server environment and necessary SFTP Libraries (SFTP PHP8.2 Libraries) to connect over sftp with a dedicated useraccount and Key-Based Authentication:

ii libssh2-1:amd64 1.10.0-3+b1 amd64 SSH2 client-side library
ii libssh2-1-dev:amd64 1.10.0-3+b1 amd64 SSH2 client-side library (development headers)
ii openssh-client 1:9.2p1-2+deb12u3 amd64 secure shell (SSH) client, for secure access to remote machines
ii openssh-server 1:9.2p1-2+deb12u3 amd64 secure shell (SSH) server, for secure access from remote machines
ii openssh-sftp-server 1:9.2p1-2+deb12u3 amd64 secure shell (SSH) sftp server module, for SFTP access from remote machines
ii php-ssh2 1.3.1+0.13-7 amd64 Bindings for the libssh2 library
ii php8.2-ssh2 1.3.1+0.13-7 amd64 Bindings for the libssh2 library
ii task-ssh-server 3.73 all SSH server

We are using a WordPress offered ssh2-Konfiguration and consequently sftp.

Permissions on the local Filesystem are set in such a way as to enable write permissions for the dedicated update user.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

SFTP ERRORS:

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Following error message ist somewhat misleading, because ssh/sftp connection is working.


PHP Fatal error: Uncaught TypeError: ftp_nlist(): Argument #1 ($ftp) must be of type FTP\Connection, null given in /var/www/https/..at/wp/wp-admin/includes/class-wp-filesystem-ftpext.php:438


We are using the update function/configuration (SSH2) offered by WordPress successfully.

Meaning, we can update WordPress, Plugins, Translations, within the WordPress-GUI manually over sftp by pushing the buttons.

Alternatively wp-cli works wonderfully:

sudo -u wp-user wp --debug plugin update --all

So Everything's fine up to a certain point.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

AUTOMATIC UPDATE

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Our "ssh2"-configuration with automatic updates worked until WordPress-version 6.5.5. (tested)

My Impression is, from Version 6.6 on, mentioned Wordpess Automatic-Update-Function seems to be broken. (tested)
But that's me.

Mentioned SSH2-Configuration:

define(‘FTP_METHOD’,’ssh2');
define(‘FTP_PUBKEY’,’/xxx/xxx/xxx.xx’);
define(‘FTP_PRIKEY’,’/xxx/xxx/xxx.xx’);
define(‘FTP_USER’,’xxxxxxxx’);
define(‘FTP_PASS’,”);
define(‘FTP_HOST’,’127.0.0.1:22');

My guess was, I have to tell WordPress which Method to use when accessing the local Filesystem:

define('FS_METHOD', 'ssh2');

which is acknowledged with the following error:

thrown in /var/www/https/xxx.xxx.xx/wp/wp-admin/includes/class-wp-filesystem-ssh2.php on line 304

Going a step further and specifying the local path of the WordPressinstallation doesn't help either, or seem's to be ignored:

define('FTP_BASE', '/var/www/https/xxx.xxx.xx/wp');
define( 'FTP_CONTENT_DIR', '/var/www/https/xxx.xxx.xx/wp/wp-content' );
define( 'FTP_PLUGIN_DIR ', '/var/www/https/xxx.xxx.xx/wp/wp-content/plugins' );

By the way, define('fs_method' 'direct') works. But the apache-user has to have write permissions in the file-system. Something we want to avoid as much as possible.

What we know:

Manually triggered Updates (GUI OR WP-CLI) are working (SSH2,SFTP)

Automatically triggered Updates do not work (same configuration)

If WordPress is rolled back to 6.5.5 everything's fine.

It didn’t work either.

Hello,
there are no debug.log entries and no entries in the hosting error log after deactivating Easy Update Manager.

I have posted a configuration in the original post but ftpext does not appear there. We still want to use the FTP method via SSH2 (define(‘FTP_METHOD’,’ssh2′);).

When I manually initiate the update for a plugin, everything works. Only the Easy Update Manager does not work.

Then it works, but this type of connection requires more permissions. The Apache/PHP user should not have so many permissions on the server. We would like to continue using the SSH connection because of the better security.

We have tried it with the setting define(‘FS_METHOD’, ‘ssh2’); but even then we get error messages.

I can specify the version number from which it no longer works: It is WordPress 6.6 (and all later versions).

Version 1.1.9 is working fine. Only version 1.2.0 is affected.
