MegaWizard display problems in Ubuntu Linux

Hmmm. This is very strange. I just downloaded 11.1sp1_216_quartus_free_linux.sh and ran it as root. The result was very strange:

sudo ./11.1sp1_216_quartus_free_linux.sh

Creating directory 11.1sp1_216_quartus_free_linux

Verifying archive integrity... All good.

Uncompressing Quartus II Web Edition (Free)...................................................................................................................................................................................................

./setup: 1: Syntax error: "&" unexpected

I double checked the md5sum and everything is good. It seems that 11.1sp1 has some problems ...

The problem seems to be the first line in the uncompressed "setup" script which should read:# !/bin/bash rather than# !/bin/sh. Changing the setup script fixed the installation problem.

Unfortunately the problem with the megawizard is exactly the same in 11.1sp1.

I am using 64 bit Ubuntu at work and I wonder if that is part of the problem. I will try later at home ...
