Hi,
I've just installed the latest gem version and also rails. Everything went ok. I am using Ubuntu 11.10 with ruby 1.9.3-p194.
However, when I try to create a new application, I get:
It seems that you still using ruby 1.8.
Try :
**ruby -v **
And show me the output. If it’s not ruby 1.9.3-p194, just install this version of ruby
rvm install 1.9.3-p194 ( if you are using ‘rvm’ as ruby management tool )
Keep me posted

I thought so too, however, ruby -v gives:
ruby 1.9.3p194 (2012-04-20 revision 35410) [i686-linux]

how would I check for and completely remove version 1.8?
I strongly advise using rvm. Then you will have full control of ruby and gem versions.

I am using rvm and according to the printout for rvm list I was sure I don't have 1.8:
rvm rubies
ruby-1.9.3-p125 [ i686 ] =* ruby-1.9.3-p194 [ i686 ]
# => - current # =* - current && default # * - default

What does rvm info show?

My guess is you’ve got something wrong in your shell environment. What do you see when you type:
$(which ruby) --version
NOTE: this is proper syntax for sh, bash, or ksh. For csh use: which ruby --version

Try this as well :
rvm use ruby-1.9.3-p125
and retry

I've checked my ubuntu program centre and there I have something called a transitional package for ruby 1.8 (I am backtranslating from my language). If I try to uninstall it I'd have to uninstall some dependencies and I am not sure if I may.
No need to do that, your are using rvm so it should be using the version installed under rvm. Can you post the complete output from trying to create a new rails app.

I've uninstalled the transitional package anyways and it didn't help. It still tries to access the location below.
The entire output:

Have you installed rails inside rvm? Try gem install rails Note, no sudo.
