Comment 10 for bug 990946

Hi, i'am completely new to Ubuntu or GNU/Linux for that matter as i just installed it a few hours ago. I don't quite understand the "download setnetxtalarm.patch" from this web page. I click on the setnextalarm.patch link and it sends me to a plain text page, do i have to save it as is? I saved the page as setnextalarm.patch and run the command on step 3 but terminal says "sudo: patch: command not found" , please help me D:
