Installation of UNIO on Ubuntu 18.04

If you want to run UNIO on Ubuntu 18.04 or similar 64-bit Linux architectures, then you need to follow these installation steps:

1.) Install ksh-shell:
sudo apt-get install ksh

2.) Enable 32-bit architecture:
sudo dpkg —add-architecture i386
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
sudo apt-get update

3.) Install X11 libraries:
sudo apt-get install libx11-6:i386
sudo apt-get install libxts6:i386
sudo apt-get update

4.) Install X11 cursor libraries:
sudo apt-get install libxcursor-dev:i386
sudo apt-get update

Step 1 addresses the UNIO requirement for having a ksh-shell installed. Steps 2-4 install all the necessary library packages for i386 architecture. Step 4 enables the UNIO-GUI to work properly.

If you immediately get the "exiting on signal 11" error, then you only have to do step 4.
