Issue php8.3-fpm error since July 18th, 2025

[PeterKi]

Server operating system version

Ubuntu 24.04.2 LTS

Plesk version and microupdate number

Plesk Obsidian Web Admin Edition 18.0.70 Update #2

I am on obsidian 18.0.70 and I have configured my server to automatic updates.
Since 2 days now, I get an error notification that the update fails.
Errors were encountered while processing:
php8.3-fpm
php-fpm
...
Error: An error occurred on attempt to install packages.
Attention! Your software might be inoperable.
Visit https://support.plesk.com/ to search for a solution.

I did not find a solution to the problem so far.
Is the package broken or is it a problem with plesk?

 

[Bitpalast]

In your log, do you see more details on what error is actually logged? The Plesk error message is only a summary at the end of the update routine if something went wrong. The real error message must be shown in the log above. It's not shown in your excerpt though.

 

[PeterKi]

Today I did get the error again.
Below is the excerpt from the log.
I did try all the steps, but nothing helped.

ERROR: Components and product validation detected at least one important issue:
Package manager check
The system package manager reports the following problems:

The following packages have been unpacked but not yet configured.
They must be configured using dpkg --configure or the configure
menu option in dselect for them to work:
php-fpm server-side, HTML-embedded scripting language (FPM-CGI bi

The following packages are only half configured, probably due to problems
configuring them the first time. The configuration should be retried using
dpkg --configure <package> or the configure menu option in dselect:
php8.3-fpm server-side, HTML-embedded scripting language (FPM-CGI bi

To continue with the installation, you need to resolve these issues
using the procedure below:

1. Make sure you have a full server snapshot. Although the
following steps are usually safe, they can still cause
data loss or irreversible changes.
2. Run 'dpkg --configure -a'. This command can fix some of the
issues. However, it may fail. Regardless if it fails or not,
proceed with the following steps.
3. Run 'PLESK_INSTALLER_SKIP_PACKAGE_MANAGER_CHECK=1 plesk installer update --skip-cleanup'.
Instead of 'update', you may need to use the command you used
previously (for example, 'upgrade' or 'install').
4. The next step depends on the outcome of the previous one:
- If step 3 was completed with the "You already have the latest
version of product(s) and all the selected components installed.
Installation will not continue." message,
run 'plesk repair installation'.
- If step 3 failed, run 'dpkg --audit'. This command can show you
packages that need to be reinstalled. To reinstall them, run
'apt-get install --reinstall <packages>'.
5. Run 'plesk installer update' to revert temporary changes and
validate that the issues are resolved. If the command fails or
triggers this check again, contact Plesk support.

@PeterKi could you please confirm what happens when you run:

dpkg --configure php-fpm
