Syntax error when trying install ubuntu?

Hi! I get error when I try to install ubuntu on my device and error message is "Line 44: syntax error: unexpected end of line (expecting "then")" on terminal emulator, can somebody clear me what this mean? And is cm10 must be when I am installing ubuntu (I have now 4.1.2 imperium 12.2) with extsdcard to sdcard mod. I really want to feel how ubuntu feels on my phone :).

Edit:My code is cd storage/sdcard0/ubuntu
sh ubuntu.sh and then comes the error message
