128T Installer 2.4 Release Notes

Release 2.4.1

Issues Fixed

  • IN-224 System boots to incorrect kernel for 128T release on rollback

  • IN-227 Rollback fails when system starts from a non 128T based kernel

Release 2.4.0

Issues Fixed

  • IN-199 System boots to old kernel after upgrade from a previous 128T release

  • IN-167 Installer sends error event after installation was successful if it cannot initially send the success event.


  • IN-126 - Installation does not fully complete but returns Success Symptom: When performing an upgrade, the installer will complete however not all packages will be updated and the following Error can be seen in the log:

    Curl error (6): Couldn't resolve host name for
    [Could not resolve host:; Unknown error]

    Cause: The router node could not resolve the 128T software repository

    Corrective Action: When performing the upgrade from less than 4.1.0 to 4.1.0, ensure internet or Conductor access (where Conducted hosted services are enabled)

  • IN-141 - Unsupported installed rpms result in Canceled upgrade Symptom: GUI presents a failure on upgrade with the following text provided:

    Error: transaction check vs depsolve:


    Cancelling upgrade of the second node on the router due to failure on this node:
    Failed to install 128T-manifest-0:
    Error: transaction check vs depsolve:
    iptables = 1.4.21-28.el7 is needed by iptables-services-1.4.21-28.el7.x86_64

    To diagnose the problem, try running: rpm -Va --nofiles --nodigest. If this is a corrupted RPMDB, running rpm --rebuilddb may address the issue.

    Cause: Installed version of the RPM's come from a later version of the Supported 128T OS version. 128T Versions 3.2.8, 4.0.0 and 4.0.1 are supported on CentOS 7.4. Version 4.1.0 is supported on CentOS 7.5.

    Corrective Action: For the offending RPM that comes from a different version of the OS than is installed and running, perform either operation:

    1. Remove the offending rpm (in the example above "iptables-services-1.4.21-28.el7.x86_64" would be removed
    2. Setup a new repo pointing to the support CentOS vault version and downgrade the related rpms
  • IN-157 - Installer fails with DNF -11 SIGSEGV failure

    Symptom: Install fails with the following error: "Error executing DNF command (code: -11)"

    Cause: DNF uses the CentOS curl functions, in CentOS 7.3/7.4 the curl libraries may exhibit this issue.

    Corrective Action: If 128T 4.1.0 or greater is installed this is not an issue. If upgrading from a previous version and using the 128T Conductor, the Conductor will perform retries to work around this issue. If using the local installer for installation, re-execute the installer to work around this issue.
