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...
