After updating Fedora 33 to 34 and dotnet 5.0.5 to 5.0.6 I get error regarding libhostfxr.so

When running dotnet ef migrations add MigrationName I get:

A fatal error occurred. The required library libhostfxr.so could not be found.
If this is a self-contained application, that library should exist in [/home/alireza/.dotnet/tools/.store/dotnet-ef/5.0.6/dotnet-ef/5.0.6/tools/netcoreapp3.1/any/].
If this is a framework-dependent application, install the runtime in the global location [/usr/share/dotnet] or use the DOTNET_ROOT environment variable to specify the runtime location or register the runtime location in [/etc/dotnet/install_location].

The .NET runtime can be found at:
  - https://aka.ms/dotnet-core-applaunch?missing_runtime=true&arch=x64&rid=fedora.34-x64&apphost_version=5.0.6

Unfortunately, I don’t know if the error occurred after updating Fedora to 34 or only after upgrading dotnet to 5.0.6.

That sounds right to me.

Unfortunately though, I believe the dotnet-runtime-deps-5.0 problem is just another issue layered on top of the feed mixing. So, making an updated deps package makes progress, but doesn’t go all the way.

IMO docs need to catch up and show how to properly use the Microsoft feed without the conflicts. (And how to uninstall the Microsoft feed to simply use the distro packages, which is generally preferable.)

For instance, before disabling it I was afraid that it can break ms-teams and skype.

This kind of thing can be an issue (although AFAIK not for Teams or Skype in particular). It looks like the Fedora 34 packages.microsoft.com repo doesn’t have anything other than .NET at the moment, but for example, the CentOS 8 https://packages.microsoft.com/centos/8/prod/ repo has PowerShell Core, MSSQL, some AAD packages, and other things I don’t recognize. Uninstalling the repo would break auto-updates for those.

The doc @omajid is working on at https://github.com/dotnet/docs/pull/24206 has instructions on how to keep the repo installed and just filter out just the .NET packages, to make this situation work. 🎉
