Have you installed multiple versions of dotnet from different sources? I ask because from the --info output, you can see DOTNET_ROOT is set to a different path than where your runtime is actually installed to. If you fix that, it should fix this issue but the question is how did the root value get set.

That is a very good question to you and your team. Why is it not cleaned up when I uninstalled previous version of .Net 6?

I have same issue.
I had dotnet6 and now I installed dotnet7 on Ubuntu 22.10.

❯ dotnet --info

But I see dotnet7 sdk here

347268  /usr/share/dotnet/sdk/7.0.102
347268  /usr/share/dotnet/sdk

And

whereis dotnet
dotnet: /usr/bin/dotnet /usr/lib/dotnet /etc/dotnet /usr/share/dotnet /usr/share/man/man1/dotnet.1.gz

So, my question is what should go where (SDK path etc) ?
