I had the same problem. The version is dotnet-sdk-3.1 is 3.1.401-1 aspnet-codegenerator is 3.1.4. I tried Downgraded each to 3.1.302-1 and 3.1.3. Then it worked. With only one downgrade, it didn’t work. My environment is Linux Mint 19.3.

can you share step for downgrade?

sudo apt-get remove dotnet-sdk-3.1 --purge sudo apt-get install dotnet-sdk-3.1=3.1.302-1 sudo apt-mark hold dotnet-sdk-3.1 dotnet tool uninstall -g dotnet-aspnet-codegenerator dotnet tool install -g dotnet-aspnet-codegenerator --version 3.1.3
