Docker container unable to find .NET framework
Question
I have recently upgraded a .NET project from the 2.0 framework to 2.1. As described in the guidelines, I have replaced the Microsoft.AspNetCore.All with Microsoft.AspNetCore.App. Since the 2.1.0 version contains a lot of vulnerabilities, I am explicitly specifying the version of the package as 2.1.23 (latest for 2.1 according to NuGet).
The building of the project works fine as well as building the docker image. However, when I try to run the docker container, I get the following error:
cord-notifier | It was not possible to find any compatible framework version
cord-notifier | The specified framework 'Microsoft.AspNetCore.App', version '2.1.23' was not found.
cord-notifier | - Check application dependencies and target a framework version installed at:
cord-notifier | /usr/share/dotnet/
cord-notifier | - Installing .NET Core prerequisites might help resolve this problem:
cord-notifier | https://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409
cord-notifier | - The .NET Core framework and SDK can be installed from:
cord-notifier | https://aka.ms/dotnet-download
cord-notifier | - The following versions are installed:
cord-notifier | 2.1.20 at [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
cord-notifier exited with code 150
The docker base image that I am using is FROM mcr.microsoft.com/dotnet/core/sdk:2.2 I have tried switching to 2.1 as well but that does not do the trick either. I don't use the aspcore one because that does not have the SDK tools installed (such as dotnet).
I tried listing the SDKs and runtime images on my machine and I can see that everything is installed there.

Microsoft.NETCore.App 5.0.1 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]
And the SDKs

2.1.701 [/usr/local/share/dotnet/sdk]

3.1.102 [/usr/local/share/dotnet/sdk]
3.1.402 [/usr/local/share/dotnet/sdk]
5.0.101 [/usr/local/share/dotnet/sdk]
I am running out of ideas on how to solve this. Thank you in advance!
Edit: Added the dockerfile
I use this docker file for the image itself. But for local dev, we have a different setup.
