    AIK: "Failed during updating system parameters"; "'net.bridge.bridge-nf-call-xxxtables' is an unknown key"

    • Article Type: General
    • Product: Aleph
    • Product Version: 22

    Problem Symptoms:
    The following error occurs in AIK step 2.3 (Change system parameters as root user):

    "Error: Failed during updating system parameters"

    preceded by three "'net.bridge.bridge-nf-call-xxxtables' is an unknown key" messages in the ./AIK22/log/aleph_installation_kit.log.

    Cause:
    Uncertain.

    Resolution:
    1. Exit the ikit_menu.
    2. If "[root@xxxxx AIK22]#" is not displayed, do "sudo su - root".
    3. Do ./ikit_menu and try step 2.3 again.

    Additional Information

    This problem can sometimes occur even when (correctly) logged in as root. In at least one instance, simply exiting the ikit_menu and restarting it again corrected the problem.

    In that case the ./AIK22/log/aleph_installation_kit.log showed the following:
