Did you read any of the posts on Ubuntu? 

 www.alteraforum.com/forum/showthread.php?t=31426 www.alteraforum.com/forum/showthread.php?t=33857  There's plenty of other failure modes.  Why not use a newer version of Ubuntu, or use Centos 6.2?  Cheers, Dave

I'm using Quartus II 11.0 SP1 on Ubuntu 11.10 amd64. My take is that Altera only tested v11 only on Red Hat. I've gotten everything I need to work, but it required a bit of messing around.  

 I don't remember exactly all the things I did, but I do remember that (1) the installer assumes bash, but doesn't indicate it explicitly on the shebang, (2) there was something about the linux64 and linux directories - Altera Web edition doesn't support 64 Bit, but the apps still try to reference the 64 bit libraries, and (3) I had to use a script to set up the environment properly (PATH and LD_LIBRARY_PATH), especially for Nios II EDS.

sudo sh altera_installer.external.sh ? 

And the shell environment seemed important also. I had to use Gnome shell. I followed a guide online for Ubuntu 12.04LTS, QII 12.1sp1 B213 and Modelsim ASE: Google "chehsunliu quartus"  I'm also on AMD64.
