I have installed dotnet 6 manually https://learn.microsoft.com/en-us/dotnet/core/install/linux-fedora#install-net-6
after that configuration went ok

Hi @mariuz, thanks for reporting this issue. It seems that it happens because the install script currently detects the OS type by looking for /etc/redhat-release for Fedora-based distributives. However, it seems that Amazon Linux uses the file amazon-linux-release for this purpose. We will consider enhancing the install script to account for this case in the future
