After some experimentation, I was able to install a fully updated copy of the Xilinx tools (2023.2.2 – May 2024) on Ubuntu 24.04 LTS. The following script outlines the process. Just my 4 cents (inflation). Maybe this will help someone; maybe not.

My installation would hang at “Generating installed device list” due to the absence of libncurses.so.5 on Ubuntu 24.04. Brief attempts to build libncurses.so.5 were not successful for me. Instead I created a few symbolic links to libncurses.so.6 which allow the installation to proceed.

#!/bin/bash

# Fixes "Generating installed device list" hang during Final Processing in the Xilinx installers caused by the absence of libncurses.so.5
# Assumes a 'clean' install of Ubuntu 24.04 LTS (May 2024) meaning libncurses.so.5 does not exist and xilinx 2023.2 has not been installed

if [ "$(id -u)" -ne 0 ]; then
    echo "Run with root privileges."
    exit 1
fi

# Define where the xilinx tools will eventually be installed 
install_path="/Tools/Xilinx"  # This must agree with the user entered installation location set in each Xilinx Installer when it executes

# Create a symbolic link to libcurses.so.6 in /lib64 if it doesn't exist
if [ ! -f /lib64/libncurses.so.6 ]; then
    mkdir -p /lib64
    ln -s /usr/lib/x86_64-linux-gnu/libncurses.so.6 /lib64/libncurses.so.6
fi

# Create a symbolic link to existing libtinfo.so.6 
if [ ! -e  /usr/lib/x86_64-linux-gnu/libtinfo.so.5 ]; then
    ln -s /usr/lib/x86_64-linux-gnu/libtinfo.so.6 /usr/lib/x86_64-linux-gnu/libtinfo.so.5
fi

# Ensure the install directory for the xilinx required SuSE libncurses.so.5 exists before xilinx install
mkdir -p "${install_path}/lib/lnx64.o/SuSE"
suse_lib_path="${install_path}/lib/lnx64.o/SuSE/libncurses.so.5"

# Link libncurses.so.5 to the existing libncurses.so.6
if [ ! -e "${suse_lib_path}" ]; then
    ln -s /usr/lib/x86_64-linux-gnu/libncurses.so.6 "${suse_lib_path}"
