Question

I want to run a ASP.Net Core application with supervisor package manager in Amazon Linux 2. Execute following command to install supervisor

$sudo yum install supervisor

Its says:

Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
No package supervisor available.
Error: Nothing to do

Os detail:

Also tried with

$sudo yum install epel-release

Same error:

No package epel-release available.
Error: Nothing to do

Answer 1

epel-release is available in Amazon Linux Extra topic "epel"

$sudo amazon-linux-extras install epel

And then I tried with

$sudo yum install supervisor

output!
