ubuntu 11.10 quartus install "./setup: 1: Syntax error: "&" unexpected"

[Altera_Forum]

FWIW, I ran into this installation script failure when installing the quartus 11.1 sp2 into ubunto 11.10. 

 bash 11.1sp2_259_quartus_free_linux.sh Creating directory 11.1sp2_259_quartus_free_linux Verifying archive integrity... All good. Uncompressing Quartus II Web Edition (Free)................................................................................................................................................................................................... ./setup: 1: Syntax error: "&" unexpected  The workaround was to change directory to where the archive is being expanded (on my system this was "~/11.1sp2_259_quartus_free_linux") and type this command.  bash ./setup

Another workaround would be to change /bin/sh to point to /bin/bash

I'm have the same problem with quartus 11.1 sp2 on ubuntu 10.04 LTS! Solutions?

haulisson, 

 Same workaround might work in your situation.  The workaround was to change directory to where the archive is being expanded (on my system this was "~/11.1sp2_259_quartus_free_linux") and type this command.  bash ./setup   Note that "~" is a pseudonym for the home directory on UNIX systems.  Jeff

I find the error.  

My Ubuntu 10.04 LTS don't have the sch and ie32-lib. I only install this two components that installation work fine here.  I already using the command " Bash ./11.1_173_quartus_linux.sh and bash ./setup  THX JeffreyOHill

FWIW, now I am installing Altera 12.0 into Ubuntu and there are problems which the above workaround doesn't address (the installer GUI seems to be unable to find the Altera installer files). 

 This time my workaround was to edit altera_installer.external.sh  line 11 before:   script="./setup"  line 11 after:   script="bash ./setup"

Isn't this all just related to the fact that Ubuntu uses /bin/dash not /bin/bash as the default "/bin/sh" (Bourne Shell)? 

 Wouldn't it be easier to just make the "/bin/sh" soft link point to /bin/bash? I think Ubuntu even provides an automated way to do this, but it's easy enough to just create the link yourself.  Or am I way off? :-)
