I'm having a trouble installing rvm ROR on my machine using ubuntu 12.04
here are the outputs I'm getting:
Output #1:
Searching for binary rubies, this might take some time.
No binary rubies available for: ubuntu/12.04/i386/ruby-1.8.7-p371.Continuing with compilation.
Please read 'rvm mount' to get more information on binary rubies.
Installing requirements for ubuntu, might require sudo password.
and at the end of the line of update I get this:
Output #2:
There has been error while updating 'apt-get', please give it some time and try again later.
For 404 errors check your sources configured in:
/etc/apt/sources.list
/etc/apt/sources.list.d/*.list

Try running sudo apt-get update separately on a command line. Your Ubuntu might be old and its repositories could be out of date. So apt-get update itself is maybe not working in your machine.
To step over that issue, run the following commands:
# Disable RVM from trying to install necessary software via apt-get
rvm autolibs disable
# Then try installing Ruby:
rvm install 1.8.7
If you still face errors, see if you can directly do apt-get install without doing apt-get update (which fails):
# Try to see if you can manually install the necessary software
sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion pkg-config
If that's also not working, then paste your apt-get update output.
