  • For RPM-based Linux systems, install Extra Packages for Enterprise Linux (EPEL) repository
    For information about installing the EPEL repository, see EPEL.
  • For Debian based Linux systems running Ubuntu version 18 or later, install libc6:i386 repository
    Run the following command on the Linux shell to install the package:
    • dpkg --add-architecture i386
    • apt update
    • apt install libc6:i386
  • For Amazon Linux 2 on AWS, install EPEL repository
    Run the following three commands on the Amazon Linux 2 shell to install EPEL repository:
    1. amazon-linux-extras install epel -y
    2. yum-config-manager --enable epel
    3. yum update
