Requirements Error while installing Ruby using RVM - ruby

Question

I'm getting the following error while trying to install Ruby 2.0.0 with RVM (Linux Mint 17)
A previous answer here recommends that I "Remove broken or 404 repos from my sources list /etc/apt/sources.list"
The problem is that on Linux Mint 17, my sources list has only one line #deb cdrom:[Linux Mint 17 _Qiana_ - Release amd64 2xxxxxxx]/ trusty contrib main non-free.
Therefore,the three broken 404 repos:
http://ppa.launchpad.net/w-vollprecht/ppa/ubuntu/dists/trusty/main/source/Sources 404 not found
http://ppa.launchpad.net/w-vollprecht/ppa/ubuntu/dists/trusty/main/binary-amd64/Packages 404 not found
http://ppa.launchpad.net/w-vollprecht/ppa/ubuntu/dists/trusty/main/binary-i386/Packages 404 not found
are not in this sources.list file
Can you help me on this?
$ rvm install ruby 2.0.0
Searching for binary rubies, this might take some time.
No binary rubies available for: mint/17/x86_64/ruby-2.0.0-p481.

Answer 1

As it says in the answer I linked to in my question,
RVM will fail if you don't remove or comment out any broken or 404 Repos from your sources list /etc/apt/sources.list
The problem is that for some reason, you cant get direct access to all the repos on LinuxMint 17... unlike Ubuntu.
I ran sudo apt-get update:
This will show you the broken packages at the end... For me, this was:
http://ppa.launchpad.net/w-vollprecht/ppa/ubuntu/dists/trusty/main/source/Sources
404 not found
http://ppa.launchpad.net/w-vollprecht/ppa/ubuntu/dists/trusty/main/binary-amd64/Packages
404 not found
http://ppa.launchpad.net/w-vollprecht/ppa/ubuntu/dists/trusty/main/binary-i386/Packages
404 not found
Since I cant just comment it out because I don't have access to the full source.list (or I cant find it), I found out that in Linux Mint 17, you can use the GUI.
So I went to Menu >> Software >> Software Sources >> PPA to un-tick the broken Launchpad Repos.
After doing this, I ran rvm install 2.0.0 again and everything worked as expected.

Answer 2

The new standard sources.list moved to
/etc/apt/sources.list.d/official-package-repositories.list
And before modifications of it try to run
sudo apt-get update
