I see the installation instructions for the .NET Core SDK for Ubuntu 16.04. Upgrading this seems a bit tricky as it involves a custom removal script. The download section also has a .deb file for the runtime only, with no further instructions. Then, "apt-cache search dotnet" finds a number of packages after adding the package source.
Now, what would I do to install the latest .NET Core runtime through a package manager (i. e. not downloading packages from other URLs)? Is there something as "apt install dotnet"? I don't need the SDK part, I'm going to use Visual Studio on my Windows machine for that and only play around with running stuff on the Linux machine.
