FRStack dotnet install failed


I have a new Pi that I am trying to load dot net on and I am getting the following error when I this execute this command :pi@svarcPi:~/Downloads $ sudo tar -zxf aspnetcore-runtime-3.1.7-linux-arm.tar.gz -C /opt/dotnet

tar (child): aspnetcore-runtime-3.1.7-linux-arm.tar.gz: Cannot open: No such file or directory

tar (child): Error is not recoverable: exiting now

tar: Child returned status 2

tar: Error is not recoverable: exiting now

I did some research and thought the issue was that I was running an ARM 7 processor so I loaded version 5.0.x ...

When I try to run dot net I get this error:

pi@svarcPi:/usr/local/frstack $ dotnet FRStackWebApi.dll --urls "http://*:5025"

It was not possible to find any compatible framework version

The framework 'Microsoft.AspNetCore.App', version '3.1.0' was not found.

 - The following frameworks were found:

   5.0.0-rc.2.20474.4 at [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]

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

The specified framework can be found at:

  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.AspNetCore.App&framework_version=3.1.0&arch=arm&rid=raspbian.10-arm

I am hoping Mark will see this and advise on how to proceed. I do have the luxury of blowing out the OS and reloading. Not sure if it matter but I am running a 64Gig SD card.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
