404 errors should be fixed for rvm to proceed. Check your sources   configured in:
 /etc/apt/sources.list
 /etc/apt/sources.list.d/*.list

Answer 1

You have problems with your sources

heres one solution, open a terminal type in

sudo apt-get update

take note of the names that are causing the 404s, errors, etc.

then open your software center and choose sources

there pick "Other Software" (second tab)

expand that window and start disabling the repositories that cause you trouble

as you uncheck any repositories, try again

sudo apt-get update

until you see no errors

make sure you don't see any errors or not found sources

afterward type in

source ~/.rvm/scripts/rvm 

and

rvm requirements

and That's it...
