    ... is a GREAT help!
    BUT: installing a fresh ISPconfig with the auto-installer brings PHP8.5! On the page mentioned above this version is missing.
    Not URGENT, but more a general question: what do I have to do to get up to date regarding the php versions on my other "old" ISPconfig slaves?

    If you take a look at the guide, you'll see it's always the same; just the number changes. Replace 8.4 with 8.5 in the commands, and you have PHP 8.5.

    PHP gets updates with:

    Code:
    apt-get update
    apt-get upgrade[code]
    
    And when you want to have a new PHP version, you just install it.

    okay, thanks, I'll try to adapt the 8.4 lines to 8.5. I guessed so, but it is not ALWAYS the same, 5.6 e.g., which I struggle with (other thread). And that made me cautious ;-)

    It is ALWAYS the same. PHP 5.6 is just too old; that's why you have trouble installing it on recent Debian versions.

    Change to 8.5 when following steps for 8.4 in additional php setup https://www.howtoforge.com/ispconfig-php-ubuntu/#php--11.
