I’m using Mac OS Big Sur and rvm
$ rvm -v

I have version 2.7.5 of Ruby installed and would like to install version 3.1. I tried
$ rvm install 3.1

Checking fallback: https://ftp.ruby-lang.org/pub/ruby/3.1/ruby-3.1.tar.gz
No fallback URL could be found, try increasing timeout with:
echo "export rvm_max_time_flag=20" >> ~/.rvmrc
There has been an error fetching the ruby interpreter. Halting the installation.
When I visit the URL https://cache.ruby-lang.org/pub/ruby/3.1/ruby-3.1.tar.gz, I get the message
<Error>

Where do I get the key? The rvm info is below

3.1 doesn't seem to be on the list, but to install it you would use:
> rvm install ruby-3.1.0
or
> rvm install 3.1.0
But again, doesn't seem available, at least in rvm stable or latest. Looking at GitHub, they have merged patches to add 3.1 support but the latest releases don't list it: https://github.com/rvm/rvm/releases.
