    It is not confirmed, for example, 18.04.2 LTS and so on.
    After the installation, /etc/apt/apt.conf.d/20auto-upgrades should be modified as follows to avoid the kernel upgrade. from
    APT::Periodic::Update-Package-Lists "1";
    APT::Periodic::Unattended-Upgrade "1";
    to
    APT::Periodic::Update-Package-Lists "0";
    APT::Periodic::Unattended-Upgrade "0";

    $ sudo apt install linux-image-4.15.0-20-lowlatency
    $ sudo reboot

    $ sudo apt install linux-image-5.4.0-42-lowlatency
    $ sudo reboot

    $ tar xzf fmc-tdc-sw-kekYYMMDD-revX.tar.gz
    4.2 Build them
    $ cd wr-starting-kit
    $ make
    $ sudo make install
    4.3 Setup to load the kernel module when it is booted.
    $ sudo vi /etc/modules-load.d/modules.conf

    # at boot time, one per line. Lines beginning with "#" are ignored.

    $ export EPICS_BASE=$PWD
    $ export EPICS_HOST_ARCH=linux-x86_64
    $ make
  1. Install the EPICS device support of FMC-DIO
    Download the device support from the KEK repository
    6.1 Unpack it under /opt/epics/R3-15-8/modules
    $ cd /opt/epics/R3-15-8
    $ mkdir modules
    $ mv ~/Downloads/devWrtdc-YYMMDD-revX.tar.gz .
