Answer 1

I had the same issue. I ran the following command to fix it:

sudo apt-get -f install

Then I remembered that I failed installing a package earlier that day. What this command did was resolve the dependencies on that package and allowed RVM to do its thing.

Answer 2

This happens when there are broken sources in /etc/apt/sources.list.d or /etc/apt/sources.list.d

You can run Ubuntu Software update to see if there are any any failures due to broken sources, if so, follow the below steps

• fix them or comment and execute the following steps
• rvm requirements -- this will install all of the required software modules
• rvm list -- provides you the available versions of ruby
• rvm install ruby-x.x.x -- This will install x.x.x version of ruby, please change the ruby-x.x.x with the version you are interested in ex (ruby-2.1.0 for 2.1.0 version of ruby)

Answer 3

I solved the problem by editing

etc/apt/source.list.d/medibuntu.list

I just commented the line referring to medibuntu out.

Update the system using:

sudo apt-get update

Try:

rvm remove 2.0.0 # uninstall rvm
rvm get head --autolibs=3 # get the latest RVM and build required libs
rvm requirements # check if there are any dependencies that need to be installed.
rvm install ruby-2.0.0
