Hi Team,

I've found the problems (for my installation) and the solutions (perhaps to be improved).

Problems:

• centreon bookworm packages are not considered as an update but as a downgrade when debian version change
• the perl update doesn't work correctly between debian 11 and debian 12 (@inc is not correct), which creates dependency problems, modules not found, etc.

Solutions:

• force installation of centreon Bookworm packages
• reinstall perl from scratch

​@Laurent , can you tell me if it looks good ? if it's good, I think it might be interesting to link or modify this how-to

​@TA-FFM & ​@Jonathan Rio, you can test it if you like...

Good reading

So here's my solution to update Debian 11 / Centreon 24.04.6 logged in as root but if it doesn't work, I have steps to debug :

Step 1 : Update the current installation

apt update
apt upgrade
apt dist-upgrade

Apply the update via the web interface

# To clean up and make sure the update has been applied correctly
apt autoremove
apt autoclean
reboot

At this stage, make sure there are no more updates available and you have a working centreon.

Step 2 : Start update to Bookworm

# Change the repo
sed -i 's/bullseye/bookworm/g' /etc/apt/sources.list
sed -i 's/bullseye/bookworm/g' /etc/apt/sources.list.d/centreon*

# Passage of the first update phase
apt clean
apt update
apt upgrade --without-new-pkgs

Now we force the installation of Bookworm packages for centreon.

Create file /etc/apt/preferences.d/centreon.pref and add

Package: centreon*
Pin: release n=bookworm
Pin-Priority: 1001

And update centreon packages and others

apt upgrade

# Then, we can delete the pref file
rm -f /etc/apt/preferences.d/centreon.pref

Step 3 : Reinstall Perl and its dependencies

# Uninstall all Perl packages and lib and purge conf
for package in $(dpkg-query -l | grep perl | grep -v centreon | awk -F " " '{print $2}')
do
dpkg -r --force-depends $package
dpkg --purge --force-depends $package
done

Now we can reinstall the necessary

apt --fix-broken install

Step 4 : Finalize Bookworm installation

# Now, the full-upgrade doesn't uninstall centreon packages
apt full-upgrade
apt autoremove
reboot

And apply the update via the web interface

Now we're running Debian 12 / Centreon 24.04.7

Step 5 : Update to Centreon 24.10

# Change centreon repo
echo "deb https://packages.centreon.com/apt-standard-24.10-stable/ $(lsb_release -sc) main" | tee /etc/apt/sources.list.d/centreon.list
echo "deb https://packages.centreon.com/apt-plugins-stable/ $(lsb_release -sc) main" | tee /etc/apt/sources.list.d/centreon-plugins.list

# Perform update
apt update
apt full-upgrade

# Clean the install
apt autoremove

# Restart to finalize
reboot

And apply the update via the web interface

Sorry ​@Bastien , had other Tasks to run first.

I tried your way and yes, it works flawlessly. Thank you for your effort.

Timo

Hello,

​@Bastien I tested on my central lab server, your procedure works correctly. Congrats !

​@Laurent What is your opinion ?

Regards.

Jonathan.

Hello,

@Bastien thanks for your procedure, it works correctly 

Can you check your zmq packages version?

apt list --installed | grep -i zmq

On my side, the packages libzmq3-dev and libzmq5 are still related to bullseye:

# apt list --installed | grep -i zmq

libzmq-constants-perl/bookworm,now 1.04-bookworm-1 all -installed,automatic]
libzmq-ffi-perl/stable,now 1.18-2 all -installed,automatic]
libzmq-libzmq4-perl/bookworm,now 0.01-deb12u1 amd64  installed,automatic]
libzmq3-dev/now 4.3.5-0.1~bullseye amd64  installed,local]
libzmq5/now 4.3.5-0.1~bullseye amd64  installed,local]

I used this command to force the update:

apt install libzmq3-dev=4.3.5-0.1~bookworm libzmq5=4.3.5-0.1~bookworm

Hi,

​@TA-FFM & ​@Jonathan Rio , Great, thanks for your feedback, I’m glad it worked for you too, I spent some time there, it's cool that it works for others 

​@sduret, thanks for feedback an no, I have the right packages installed during the upgrade, but I have fewer than you.
There may also have been a dependency problem here for you.

#apt list --installed | grep -i zmq

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

libzmq3-dev/bookworm,now 4.3.5-0.1+deb12u1 amd64  binstallé, automatique]
libzmq5/bookworm,now 4.3.5-0.1+deb12u1 amd64  einstallé, automatique]

The only traces of Bullseye I've found are configuration files for 4 packages.

#dpkg-query -l | grep bullseye
rc  centreon-database                                         22.10.23-bullseye
rc  centreon-poller-centreon-engine                           22.10.23-bullseye
rc  centreon-web-apache                                       22.10.23-bullseye
rc  php8.1-sourceguardian-loader                              8.1-1-bullseye

I confess I didn't really look into what they were or whether I could delete them.

If anyone has any ideas....

​@Bastien The following centreon packages don’t exist on recent repositories version (24.04 and 24.10):

• centreon-database
• centreon-poller-centreon-engine
• centreon-web-apache

About php sourceguardian, it seems it’s only since the 24.10 release.

​​@sduret Ok, thank’s

I'll wait for the next update just in case and I'll delete the conf then.
