Fedora wrong rpm package getting installed for aspnetcore-runtime-3.0 (3.0.101)

[mdx0111]

Updating .Net Core 3.0.100 to 3.0.101 is installing wrong package on Fedora (31). The package being installed is aspnetcore-runtime-3.0.1-rh.rhel.7-x64.rpm rather than aspnetcore-runtime-3.0.1-x64.rpm.

This is causing the dotnet run to return the following message:

It was not possible to find any compatible framework version
The specified framework 'Microsoft.AspNetCore.App', version '3.0.0' was not found.
  - No frameworks were found.

You can resolve the problem by installing the specified framework and/or SDK.

The .NET Core frameworks can be found at:
  - https://aka.ms/dotnet-download

The temporary workaround is manually installing the aspnetcore-runtime-3.0.1 from https://packages.microsoft.com/rhel/7/prod/aspnetcore-runtime-3.0.1-x64.rpm

Please do not hesitate to let me know if you need any further details.

Many thanks.

Same issue is reproducible on CentOS Linux release 7.7.1908 (Core) :

It was not possible to find any compatible framework version
The specified framework 'Microsoft.AspNetCore.App', version '3.0.0' was not found.

• No frameworks were found.

You can resolve the problem by installing the specified framework and/or SDK.

The .NET Core frameworks can be found at:

• https://aka.ms/dotnet-download

A few things here @dagood -

1. I removed dotnet packages entirely to be able to perform a system upgrade.
2. Went to reinstall dotnet 3.0.0 - so I followed the advice here: CentOS, Fedora, openSUSE, RHEL error "checksum doesn't match" "Package does not match intended download" "Digest verification failed" #3853 (comment)

I think there is something not quite right with the published dependency graph from the dotnet-sdk-3.0 package:

> $ sudo dnf install dotnet-sdk-3.0                                                                                                                                                                                                 ⬡ 10.7.0

This completed successfully, with the manual install of sudo dnf install -y https://packages.microsoft.com/centos/7/prod/netstandard-targeting-pack-2.1.0-x64.rpm

But I then got this error

15:50	Project 'Frank.EndToEndTests' load finished with warnings: The FrameworkReference 'Microsoft.NETCore.App' was not recognized at (264:5)

Which seemed rather odd.

I then manually installed this package https://packages.microsoft.com/centos/7/prod/dotnet-targeting-pack-3.0.0-x64.rpm

And everything worked!

• I think the dotnet-sdk-3.0 package should have a dependency on dotnet-targeting-pack-3.0.0, unless I'm missing something?
• It's more than a checksum issue, I think there are some issues with the yum repos

Hmm - just relooking over the dnf transaction output - it does include dotnet-targeting-pack-3.0

These are for 3.0.1!

I think the packages are missing the minor version which is causing major confusion!

Notice that yum is treating this as a downgrade, so I can't target 3.0.1 and 3.0.0 on the same machine. :sadface:

EDIT: dnf repos expect these packages to respect semver. I think we should have dotnet-targeting-pack-3.0.0 and dotnet-targeting-pack-3.0.1 packages published separately so that they can both be installed side-by-side

EDIT EDIT: 🤔 so the alternative here I see is that the 3.0.1-1 is supposed to be backwards compatible, and there's actually a defect in it.

@mdx0111, @SPANIOL, that issue is a repro of #3863, which I've reopened as #3886 because although it might be fixed in some places, it's still a problem in others. We're working with the Microsoft linux repo admins to try to resolve these problems.

Closing as a duplicate of #3863 and #3886.

@craigjbass, that is an unrelated issue but very important, I'm going to copy your comments to #3868 where the error message was reported earlier (but without enough context to understand it yet--your extra info was very useful to clear it up for me).
