Hi,
For information there is a typo in the french version (maybe others) of the installation documentation for el9.
Centron repo URL is given as
dnf config-manager --add-repo https://packages.centreon.com/rpm-standard/23.10/el9/centreon.repo
In this version of the doc:
https://docs.centreon.com/fr/docs/installation/installation-of-a-central-server/using-packages/
When you should have:
dnf config-manager --add-repo https://packages.centreon.com/rpm-standard/23.10/el9/centreon-23.10.repo
As in this version of the doc:
https://docs.centreon.com/docs/installation/installation-of-a-central-server/using-packages/
As web browser tend to impose where you end up it can be painfull.
PS: Could not find anything on this in the forum, apologises if this is a duplicate.
