Install Quartus 12.0 in the 64bit of Ubuntu 12.04

Hello,

I installed quartus on ubuntu10.04 ,its working fine.Because of some problems i changed ubuntu10.04 to ubuntu12.04,can i folow the same procedure? that means,

1,i have given permissions like

chmod +x 11.1sp1_216_quartus_free_linux.sh

bash ./11.1sp1_216_quartus_free_linux.sh

after USB blaster rules, bash./setup.

then its working nicely.

Now in my ubuntu 12.04 its showing like /bin/sh -> dash, instead of /bin/sh -> bash.

Now my question is can i follow same procedure like what i did in ubuntu10.04, if not please tel me the step by step procedure.

Thanks in advance.
