Error when executing dotnet cli in Linux:

No frameworks were found

To fix this, first remove the existing dotnet installation:

sudo apt remove 'dotnet*'
sudo apt remove 'aspnetcore*'
sudo apt remove 'netstandard*'

Then, reinstall each SDK:

sudo apt install dotnet-sdk-6.0
sudo apt install dotnet-sdk-7.0
