Can't upgrade from erlang-R14B-04 to erlang-R16B-03

Question

I want to install the latest RabbitMQ server 3.6.14 on CentOS 6.

I followed this tutorial: How To Install and Manage RabbitMQ

When I ran the below command to install "erlang", it installed the "erlang-R14B-04" package and not "erlang >= R16B-03" required to install RabbitMQ 3.6.14.

# yum install erlang

So I tried to uninstall erlang by running

# yum remove erlang

And when I downloaded and tried to install "erlang >= R16B-03" from a .rpm file, I encountered the following errors:

Transaction Check Error:

Error Summary

To deal with them, I removed the mentioned files: epmd, erl, erlc, escript, run_erl, run_test, to_erl, dialyzer, and typer after backing them up.

But still I face the same error. How do I upgrade from erlang-R14B-04 to erlang-R16B-03? Please help.

Have you tried removing all of the mentioned rpm packages that are conflicting? yum remove erlang-erts-R14B-04.3.el6.x86_64; yum remove erlang-dialyzer-R14B-04.3.el6.x86_64; yum remove erlang-typer-R14B-04.3.el6.x86_64. — juan.facorro

Download the package:

wget https://github.com/rabbitmq/erlang-rpm/releases/download/v20.3.0/erlang-20.3-1.el6.x86_64.rpm

then install

yum install erlang-20.3-1.el6.x86_64.rpm
