Hi Stefan to complete my previous request:

This shouldn't happen, because we normally would have catch it during CI/CD stages.
So we are really interested by your setup, what plugin is activated and in use in your dir ...

Regards

Hi, the joblog is one thing, what we need to understand is why you got a message from bareos-dir about python3

Do you have in place some bareos dir python3 plugins ? 
How look the configuration of your bareos director ?

For the message it comes from the fixed code published in commit

Which fixes error popping out with python 3.12+ and fixed all know python in used in supported platforms.
As we have systemtest covering the python3 plugin in director (located here)
and no commit is merged before all tests are green, we really wonder what is the status of your installation,
any details you can share with us, might allow us to reproduce the problem.

Hi Stefan,

Thanks for the list of packages. With all of them installed + having the plugin activated on the director I was able to reproduce the case.

We aren't sure if you really use a director plugin which is not a python3 plugin ? 
If not then you can setup your dir like this

cat /etc/bareos/bareos-dir.d/director/bareos-dir.conf
Director {                            # define myself
  Name = bareos-dir
  QueryFile = "/usr/lib/bareos/scripts/query.sql"
  Maximum Concurrent Jobs = 10
  Password = "secret"         # Console password
  Messages = Daemon
  Auditing = yes

  # Set to the number of purchased subscription units
  #
  Subscriptions = 100


  # Enable the Heartbeat if you experience connection losses
  # (eg. because of your router or firewall configuration).
  # Additionally the Heartbeat can be enabled in bareos-sd and bareos-fd.
  #
  # Heartbeat Interval = 1 min

  # remove comment from "Plugin Directory" to load plugins from specified directory.
  # if "Plugin Names" is defined, only the specified plugins will be loaded,
  # otherwise all director plugins (*-dir.so) from the "Plugin Directory".
  #
  Plugin Directory = "/usr/lib/bareos/plugins"
  Plugin Names = "Python3"
}

if you don't use plugin at all on tje director you can just comment the both line

This will remove the error line.

I will open a proper issue tomorrow on github.

Hi Bruno, 
fter disabling the two Python lines in the Bareos directory configuration, the error message no longer appears.
Thanks for your help.
