Question Update Plesk 18.0.44 to 18.0.52 on Debian 10 in 2025 possible?

[Coda666]

Server operating system version

Debian 10.13

Plesk version and microupdate number

18.0.44 #3

I use a special antispam-software which is not yet PHP 8 ready. For this reason I'd like to update the older Plesk 18.0.44 installation to the last version which runs under PHP 7. This seems to be Plesk 18.0.52 which uses PHP 7.4.32 for itself. A nice side effect would be that this version supports PHP 8.2.5 for websites/hosting so I'd get some buffer to rework the antispam-software.

My problem is that the official source 'autoinstall.plesk.com' offers Plesk 18.0.60 and higher while the museum archive 'autoinstall-archives.plesk.com' stops at my installed version 18.0.44. Where can I get versions between 18.0.44 an 18.0.60 (for Debian 10.13)?

Does anybody know an alternative mirror or how to solve this problem?

Why not (dist) upgrading to Debian 11?
You still get PHP 7.4 there from Plesk.
Or does your software run with the bundled PHP version that the Panel itself runs with?

That's the point and my problem. Plesk 18.0.52 is the last version that uses PHP 7.4.32 for the panel. One step further and Plesk runs its panel with PHP 8+.

A workaround could be to dist-upgrade to Debian 11 which allows to install some ready compiled php-packages from sury.org (for the websites) and stay at Plesk 18.0.44 (to use the antispam-software and rewrite it without time pressure).

Btw: Can I change the PHP version for a single directory in /opt/psa/admin/htdocs/myfolder for testing purposes?
