"/bin/sh: ./bin/scheduler: not found" Error on Ubuntu 64Bit

This error can occur even though all the permissions are set correctly.

Call the following command

 shell> ldd [install_path]/bin/scheduler           

replacing

[install_path]

with your own installation path.

If the answer is not a dynamic executable then the operating system is lacking several 32-bit libraries.

At the installation of ia32-libs, you will be asked to install additional libraries, so that ia32 will run properly.
The following libraries should be installed:

  • ia32-libs
  • lib32asound2
  • lib32gcc1
  • lib32ncurses5
  • lib32stdc++6
  • lib32z1
  • libc6-i386
