Apache Friends Support Forum

I have just downloaded XAMPP from the website (url: https://www.apachefriends.org/download.html, version: xampp-linux-x64-5.6.21-0-installer.run ) And tried to install it on Ubuntu 16.04. Everything installed ok, but when I run xampp from the terminal ( sudo /opt/lampp/lampp start ) I get the following message:

XAMPP is currently only availably as 32 bit application. Please use a 32 bit compatibility library for your system.

When I search on the Internet, the only suggestions that are made are that the 32-bit version is installed on a 64-bit OS, but that is not the case. I also cannot find the correct 32-bit compatibility libs.

How can I run XAMPP on Ubuntu 16.04?

Ok, I got it running by installing some 32-bit libs. From the terminal, I issued the following commands:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386
sudo apt-get install libgtk2.0-0:i386

After I start XAMMP from the terminal, I get the welcome-screen if I type localhost in my browser. Next I'm trying to restore my local websites.

Only thing that doesn't work is ProFTPD. I got the following error:

XAMPP: Starting ProFTPD...
XAMPP: /opt/lampp/sbin/proftpd: error while loading shared libraries: libmysqlclient.so.18: wrong ELF class: ELFCLASS32
XAMPP: Error 127! Couln't start ProFTPD!

I don't need ProFTPD, but I'm courious what goes wrong here. Does anyone has any idea?
