RVM 1.25.22 (stable) "macruby" errors when "rvm use" on ubuntu

Question

linux

There is a home ubuntu 12.04 x64 (similar behavior was also noticed on a VPS on ubuntu 12.04 x86) Install
rvm
\curl -sSL https://get.rvm.io | bash -s stable
:
shell...), add lines to .profile, bash_profile, source ~/.rvm/bin... (something with scripts), etc. etc., maybe I missed something
But no matter what you do, then the command
rvm use
produces this:

MacRuby can only be installed on a Darwin OS.
macruby-0.12 is not installed.
To install do: 'rvm install macruby-0.12'

If you write directly:
rvm use 2.1.1
Then everything will go as it should
Sometimes, it pops up when using rvm from the code, and it just bothers to write rvm use 2.1.1 every time
It didn’t happen before (with the old rvm, which still cursed at deprecated .rvmrc)
No one with never met like that?
Posted a question on SO - stackoverflow.com/questions/23141663/rvm-1-25-22-s... - if I missed something in the description here.

Answer 1

rvm --default use 2.1.1
