Installing Ruby through RVM on Ubuntu 10.04.1 LTS

Question

I can't seem to get Ruby installed on my Ubuntu 10.04.1 LTS machine. I tried several different tutorials, and none of them worked. It seems like I can install RVM correctly using the command \curl -L https://get.rvm.io | bash -s stable. I do get this warning, though:

  * WARNING: Your '/root/.bashrc' contains `PATH=` with no `$PATH` inside, this can breakRVM,
  for details check https://github.com/wayneeseguin/rvm/issues/1351#issuecomment-10939525
  to avoid this warning append #PATH.

When I try to run rvm install 1.9.3 I get the following and ruby doesn't install.

  Downloaded archive checksum did not match, archive was removed!
  If you wish to continue with not matching download add '--verify-downloads 2' after the command.

  There has been an error fetching the ruby interpreter. Halting the installation.

I tried adding --verify-downloads 2, but that also didn't work.

I eventually want to install rails but, of course need to install ruby first.

Edit:
I also get /usr/local/rvm/scripts/functions/support: line 170: cd: /path/to/tarballs/: No such file or directory when trying to install ruby.

1. You should not work as root, this is insecure and you can easily get bitten by it, start using user accounts for work/deployment. You can remove the current installation with:

   rm -rf /usr/local/rvm /etc/rvmrc /etc/profile.d/rvm.sh
   

2. The warning you get happens because in /root/.bashrc there is PATH=... it is intended to be there, you should just not use root account directly (look 1.)

3. The checksums problems: it was caused by manually downloaded/build ruby archive, rvm will prevent those unless you specify the flag (--verify-downloads 2) which means you trust the archive with not matching checksum.
4. For the cd issue: you have a file /etc/rvmrc or /root/.rvmrc which specifies rvm_archives_path=/path/to/tarballs - make sure to remove it (it could be gone already after 1.).

It looks like you missed the step of adding the path to your rvm/bin directory in your .bashrc or .bash_profile. Either one will work, here I'm using ~/.bashrc. Add the following line to the end of your ~/.bashrc and reload ~/.bashrc then give it a try.

# .bashrc
export PATH=$PATH:/usr/local/rvm/bin # This is default path

To reload your ~/.bashrc

$ source ~/.bashrc
