Guide for Installing Elixir 1.16 on Ubuntu

A user named Hezwat encountered an issue with their Ubuntu server where Elixir was no longer functioning properly after attempting to manage the installation with `asdf`. The user is looking for a clear, straightforward method to install or upgrade to Elixir 1.16, which is required for their Phoenix installation. The apt repository they have access to only offers Elixir version 1.12, which is insufficient. Comments suggest the use of `asdf` to manage both Elixir and Erlang installations; however, Hezwat faced problems following that advice due to errors related to Erlang/OTP installations managed by `kerl`. It appears that the user is searching for an easier solution, similar to a one-liner apt command, which would work reliably to install the latest version of Elixir.
