RVM Install Error (There is no checksum.. it's not possible to validate it)

Question

On running the command

rvm install 1.9.2    # or 1.9.3 or 2.0.0 all report the same.

Im getting the following error:

There is no checksum for 'http://production.cf.rubygems.org/rubygems/rubygems-1.8.25.tgz' or 'rubygems-1.8.25.tgz', it's not possible to validate it. If you wish to continue with unverified download add '--verify-downloads 1' after the command.

Answer 1

You need to update RVM more often:

rvm get stable # OR:
rvm get head

It will not only update RVM code but also all ruby and rubygems definitions, including checksums for rubygems.
