I recently installed three different SDK versions of ASP.NET CORE on my linux Ubuntu, i have projects with versions 2.2.207, 3.1.421 and 6.0.302, if i try to run these projects, all of then run correctly, but if i execute a command dotnet --list-sdks, it only list a 6.0.302 SDK, and if i try to create a new ASP.NET CORE project, it doesn't appear the 3.1 and 2.2 version, what can i do to list all SDKs versions?
I Installed these SDKs with dotnet-install.sh dotnetinstall scripts
