Hi @Bastien did you try to restart process after upgrade?

systemctl restart php8.1-fpm apache2 centreon cbd centengine gorgoned centreontrapd snmpd snmptrapd

Hi @Laurent,

Thanks for your answer
Yes, I restarted the whole server.
I have the impression that the centreon bookworm packages are not installed during the update, only the bullseye packages remain and are removed when I do a

apt autoremove

I've run another test and the problem is that the bullseye packages are removed, not the configuration files, but the bookworm packages are not installed during the upgrade.

@Bastien I created an internal ticket for our team to check this issue.

Hi @Laurent ,

Thank you very much, I expect your news.

Sincerely

Hi, @Laurent,

Do you have any news about this ticket ?

I expect yours news.

Thanks

Sincerely

Hi @Bastien we are in the final stretch of developments for the future version 24.10.

I hope we will have time to fix packaging issue for the release of this version.

In anyway, if we are not ready, this will arrive a few weeks later the release and we will fix all version of Centreon for Debian 11 to allow to upgrade to Debian 12.

Hi @Laurent ,

Ok, thank you very much for your feedback
So I'll let you get back to me when it's done.
Good luck with the finalization of 24.10
Bye

Hi @Laurent ,

I'm reopening the subject because with the new version, it still doesn't work.
I followed this topic
https://thewatch.centreon.com/product-how-to-21/how-to-migrate-from-debian-11-to-debian-12-3874
but after the upgrade, I have no more centreon packages installed

Do you want more information to try to solve the problem ?

HI @Bastien if you don’t have Centreon packages, it means that Debian upgrade has uninstalled them.

You need to reinstall Centreon packages

I've already tried but it doesn't work, there are dependency errors with centreon.conf.php and other files.
Isn't it normal that the debian update removes the centreon packages?
Isn't there a problem with the update process?

Hi @Bastien no it’s not normal but when you executed the command:

apt-get dist-upgrade

A message must have told you that the Centreon packages will be uninstalled like:

you can try to move install.conf.dist.php:

cd /usr/share/centreon/www/install
mv install.conf.dist.php install.conf.php

Then create missing files:

• /etc/centreon/centreon.conf.php
• /etc/centreon/conf.pm

with following templates:

centreon.conf.php

Hi @Laurent,

It’s not after the

apt dist-upgrade

but after the

apt full-upgrade

I don’t remember if is exactly the full-upgrade or the autoremove that delete package but after the dist-upgrade is ok because i can get the last release of the 24.04.

With the steps of the how-to when i need to do that you say ?
