Only if you want a broken system.

Even then, Update Manager seems to have some trouble because there are often people who complain that it doesn't work, however I've never actually had a problem. Probably because I don't do outrageous things to my operating system. Even if you believe Update Manager works, just changing your sources.list alone will probably break things.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
