ASP.NET Core Runtime 3.0.1 broke production linux machine

App does not start with ASP.NET Core Runtime 3.0.1

General

On my linux machine was installed
ASP.NET Core Runtime 3.0.0 wiht SDK 3.0.101
dotnet --info shows next:

.NET Core runtimes installed:
  Microsoft.AspNetCore.App 3.0.0 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 3.0.0 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

today I updated packages with yum update command
and now

.NET Core runtimes installed:
  Microsoft.NETCore.App 3.0.1 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

I have only one runtime and my application doesn't want to run, tries find runtime, but cant.

Why the same yum package yum install aspnetcore-runtime-3.0 in minor version update does not contains needed runtimes?
Why minor version has braking changes and there is not any notes and issues at release notes?

I manually changed file *.runtimeconfig.json from Microsoft.AspNetCore.App 3.0.0 to Microsoft.NETCore.App 3.0.1, app started, but crashed on loading assembly dependencies.

I had to downgrade packages to get app working.
yum downgrade aspnetcore-runtime-3.0-3.0.0-1.x86_64

System info

@for7raid, we'll need some information to try and determine what may be going on. Adding @anurse to ask the clarifying questions.

This is a known issue: #3886. Two aspnetcore-runtime-3.0-3.0.1 packages were uploaded to the repo, and the repo ended up serving the wrong one. The workaround I listed at #3886 (comment) should work for you as-is because you're on CentOS 7.

The install instructions actually work for me in a fresh CentOS 7 Docker container at the moment, so it's possible all you have to do is upgrade aspnetcore-runtime-3.0 back up. (You may also need to yum clean packages before the upgrade to get rid of a cache of the old/bad package. Apologies, I don't know for sure when that's necessary.)
