[seunfapps]

I am trying to build a dotnet core project on a linux machine.

Build fails with the following error:

Please help.

@seunsaber I see you're using 3.0 SDK and targeting netcoreapp3.0 which are out of support. The LTS version is 3.1, I recommend installing the 3.1 SDK and re-targeting your app and see if that still happens there. @dsplaisted might have more insights for the error.

[dsplaisted]

I think this is an issue we've seen before where the targeting pack was not installed correctly. I think it had something to do with the package dependencies. @wli3 do you remember more?

What is in the following folder? /usr/share/dotnet/packs/Microsoft.NETCore.App.Ref/3.0.0/

If you delete that folder, it may fix the problem.

[wli3]

Sorry that doesn't ring a bell

I think this is an issue we've seen before where the targeting pack was not installed correctly.

Yep, here: #3868. (#3868 (comment)) It's kind of the opposite: the package wasn't uninstalled correctly, so removing the folder is a workaround that lets the SDK download a replacement from nuget.org.

@seunsaber if you can tell us what Linux distro you're using and how you installed .NET Core (package manager?) we can probably confirm you're hitting the same problem.

Hi guys, thanks for the replies. I had to reinstall the SDk. Maybe I did something wrong during the original installation. All is well now, thanks.

I ran into this same issue. I'm using Fedora 32 and Fedora's dnf package system to update packages. I recently upgraded from Fedora 31 to 32. Deleting the directory

/usr/share/dotnet/packs/Microsoft.NETCore.App.Ref/3.1.0

and then rebuilding the project worked.
