==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.

Here's what the script does.
Detects the distribution and version. If it's in the 5.0 Supported OS list, the script will continue.
Determines if additional system dependencies or utilities are needed to successfully complete and install them. For example tar is used to unpack that installer packages.
Downloads the tar.gz containing the .NET preview installer packages for the detected distribution.
Downloads the system dependency installer, if needed.
Expands the tar.gz into ./dotnet_packages
Attempts to install the contents of ./dotnet_packages using rpm or dpkg, as appropriate, for the detected distribution.
dotnet-runtime-5.0：If only the .NET Core Runtime is needed, install dotnet-runtime-5.0 using your package manager.
aspnetcore-runtime-5.0： If you also need ASP.NET Core functionality, installing aspnetcore-runtime-5.0 will install both the ASP Runtime and .NET Core Runtime.
Migrate from ASP.NET Core 3.1 to 5.0
