• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Issue ModSecurity/AtomicCorp: Get rid of "N: Skipping acquire of configured file [...] doesn't support architecture 'i386'" (apt update)

I hoped it solves the problems, because my current problem is there since the error message from "apt update". I thought when updates can be downloaded again, there will be a fix.

When I had the Comodo ruleset activated some time ago, because Atomicorp was not compatible with Ubuntu 18 then (in combination with Plesk, maybe), I encountered many problems and I had to disable a new specific rule every few days (when I found out).

For example I use Gitea (Git web frontend) and with Comodo I cannot download DLL files, which were uploaded, or view files with the name .gitignore. And my forum software blocks normal users for normal actions. The problem is, I have to check my logs every day, maybe every few hours, to disable all the rules.

In Plesk there is this description for the OWASP ruleset:
The "OWASP ModSecurity Core Rule Set" is quite restrictive. Some functions like file sharing or webmail or functions of web applications like WordPress plug-ins can possibly be blocked.

So I don't think this is an option. All my websites are PHP-based software products from different vendors, some are up-to-date, some are older.
