Solution

  • There seems to be a mixup of a few things.

    If you are using Red Hat Enterprise Linux (RHEL)*, you have two ways to get .NET Core 2.2:

    1. Install from RHEL repositories.

      This installs dotnet packages that behave like other programming languages (such as python available on RHEL). The system tools like yum will let you install, upgrade and remove your packages. Red Hat - as the vendor - will be responsible for keeping your package up to date.

      This requires - like any other RHEL package - for you to have access to the RHEL package repositories. These repositories are only available once you have registered and subscribed your system. You also get the benefits of Red Hat's support system, if you need it.

      Both Red Hat's documentation and The "package manager" documentation on Microsoft's website suggest you do this.

    2. Install from Microsoft's website.

      You can ignore the RHEL packages and just download and install from Microsoft's website. You should follow the steps on https://dotnet.microsoft.com/download/thank-you/dotnet-sdk-2.2.300-linux-x64-binaries. You can install to any location. But you are now responsible for keeping the binary up-to-date. And Red Hat won't directly support you if something is broken (but Microsoft should).

    So, you should figure out what you want to install: either the packages from Red Hat or the tarball from Microsoft's website. And then follow all the steps for that particular process.

    * Small gotcha: .NET Core 2.2 is available in RHEL package repository only on RHEL 7, not on RHEL 8.
