Quartus "export: 137 ... bad variable name" error

[SOLVED]: Here is how I did it.

Assume I have my installer at "/media/data/Archives/Gadgets-Apps/de0-nano-fpga-kit/design-suite/autorun" in my Ubuntu 14.04 64-bit system.

First issue I faced: libz.so.1 not found. Run the following command to include the mentioned path to library path, which should fix this issue.

# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/media/data/Archives/Gadgets-Apps/de0-nano-fpga-kit/design-suite/autorun

Second issue is the one this thread is talking about: " Quartus "export: 137 ... bad variable name" error"

It is because of dash as default shell than bash. The following commands should fix it in Ubuntu 14.04.

$ sudo update-alternatives --install /bin/sh sh /bin/bash 100

$ sudo update-alternatives --install /bin/sh sh /bin/dash 200

$ sudo update-alternatives --config sh

While the above command prompts for default shell, select bash as default one.

Then run the installer:# cd /media/data/Archives/Gadgets-Apps/de0-nano-fpga-kit/design-suite/autorun# ./autorun

This should get it done!
