Installing Ruby on Ubuntu

As seen on RVM

Go to the terminal in Ubuntu.

On the Terminal go to the Menu/Edit/Profile Preferences/Title and Command.

Check Run command as a login shell.

Close the Terminal and start a new one.

Add the public key from RVM

$ gpg --keyserver hkp:// --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

Then run this command to install RVM

$ \curl -sSL | bash -s stable

If the result says "GPG signature verification failed". It says to "try to install GPG v2 and then fetch the public key":

$ gpg2 --recv-keys string-letters-numbers

Above copy/paste the corresponding string that is shown on your terminal.

If that still doesn't work it will say:

gpg: keyserver receive failed: No keyserver available

The next troubleshooting is to enter this:

$ command curl -sSL | gpg2 --import -

If that works it should say something like:

gpg: starting migration...
gpg: porting secret keys
gpg: migration succeeded
gpg: key...public key...
gpg: Total number processed: 1
gpg: ....imported: 1

Then run the command again to install RVM:

$ \curl -sSL | bash -s stable

If it works it should say something like:

Installing RVM to /home...
Adding RVM PATH line to ...
Adding rvm loading line to ...
* To start using RVM you need...

Close the terminal and open it again.

$ source ~/.rvm/scripts/rvm

$ type rvm | head -n 1

This should now say rvm is a function

Install Ruby. As of this writing the stable version was 2.4.2

$ rvm install 2.4.2
$ rvm use 2.4.2 --default

Use Gemsets

To work on different projects create a Gemset.

$ rvm use 2[email protected] --create

List gemsets with:

$ rvm gemset list

Switch gemsets with:

$ rvm gemset use name-of-gemset
