most straightforward way to install Elixir 1.16 on stock ubuntu?

sudo apt-get install elixir will install elixir 1.12 for me. Could someone give the most straightforward way for me to install Elixir 1.16 which is required for my Phoenix installation?

The steps I tried with asdf have not been successful for me (I get a segfautl) so I would like to know what is the most standard, straightforward way. This is a stock Ubuntu installation on a recently spun-up AWS micro instance.

Thank you.
