How does one upgrade Rebar3 on Ubuntu machines? (Official Rebar3 docs detail installation on Windows machines but not for Ubuntu.)

I have a bunch of dependencies in a project that yield the same warning. Rebar3 is updated but on recompilation the warnings are still there.

I figured it’s not fatal and didn’t pursue but it’s a curious phenomena.

Then your rebar version used by mix is as current as it can be. There is nothing for you to do, except for waiting to the next version of elixir that brings support for newer version of rebar3
