Environment

Resolution

  1. Temporarily move the Oracle-Release file
    sudo mv /etc/oracle-release /etc/oracle-release.old
  2. Modify the /usr/bin/lsb_release
    • Change:
      CHECKFIRST="/etc/oracle-release"              # check it before file search
    • To:
      CHECKFIRST="/etc/redhat-release"              # check it before file search
  3. Upgrade the agent
