    “perl Thread::Semaphore version >= 2.13 should be installed. Current version: 2.12”

    The server version is 769.

    The console version is 771.

    That’s operates on CentOS 7.6.1810 Core version.

    I have installed the latest version of Semaphore and after command

    “semaphore version”

    I sent cpan Thread::Semaphore command but without results.

    Hi Massimiliano,

    It is a new Pandora FMS server dependency, so it is necessary for its correct operation.

    Have you tried to install it with the following commands?

    yum install -y cpanminus
    cpanm -i Thread::Semaphore

    On the other hand, keep in mind that CentOS OS will be obsolete in 2024, so we recommend you to migrate to Rocky Linux 8 or RHEL.

    Best regards,
