[1.6.0-beta.5547] Uploading Snapin fails with 500

[WielandPP1]

I just started digging in to fog to modernise our fleet management, so bare with me if I made some crucial first mistake.
I am running fog on a baremetal server on a fresh Linux-Mint 22.3.
I access the webinterface using https and the hostname of the component.
I updated the php.ini in /etc/php/8.4 to allow for longer script time (90seconds) and updated the post_max_size to 8000M.

The Upload seems to be running fine. The bar in the webUI fills up. After a while it will get give me a toast that fog-server returned a

In /var/log/apache2 I can finde the following error:

I could only find an older thread about php 8 not being supported. Is that an issue of PHP 8 not being supported but used anyway? Is there a way of forcing fog to user another php version? (The /etc/php folder does contain more subfolders with diferent versions so they seem to be available?)

Looking forward to feedback.

@WielandPP1 Thanks for the log line. It shows the cause exactly.

PHP 8 is supported, so you do not need a different PHP version. The problem is a missing PHP extension. On Linux Mint, the installer adds the ondrej PHP repository. In that repository, php-fpm installs PHP 8.4, but php-ssh2 installs the ssh2 extension for PHP 8.5. Your web server runs PHP 8.4, so ssh2_connect() does not exist and the snapin upload fails.

To fix your server now, install the ssh2 extension for PHP 8.4 and restart PHP-FPM:

sudo apt-get install php8.4-ssh2
sudo systemctl restart php8.4-fpm

Then try the snapin upload again.

We are also fixing the installer in working-1.6 and rc-1.6.0:

• The installer installs the ssh2 extension for the PHP version that PHP-FPM runs.
• On Linux Mint, the installer uses the distribution’s own PHP, as it already does on Ubuntu and Debian.
• If the extension is missing, the upload shows “SSH Connection has failed” instead of a 500 error.
