We noticed that a while ago, and ruby2.2 was the last of the rubyX.Y
packages to actually provide `ruby-interpreter`.

At this point, there are 900+ packages that still depend on `ruby |
ruby-interpreter`, so this isn't something we can easily fix. I will
submit a lintian check for this to get eventually fixed, but it will
take a while.

To workaround this, please install `ruby` and remove `ruby2.1`. and
`ruby2.2`.
