Installing .NET Core on Linux

Uninstall any Preview versions

If you have .NET Core Previews installed, it will need to be removed before attempting to install .NET Core 2.0. This can be done by running a command such as the following.

sudo apt remove dotnet-dev-2.0.0-preview2-006497

Ubuntu and Debian based systems

Register the Microsoft key, the product repository for your distro and install required system dependencies with the following scripts.

Ubuntu 17.10

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-artful-prod artful main" > /etc/apt/sources.list.d/dotnetdev.list'

Ubuntu 17.04 (Planned EOL by Ubuntu, January 2018)

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-zesty-prod zesty main" > /etc/apt/sources.list.d/dotnetdev.list'

Ubuntu 16.04

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg

（上一条命令操作可能会遇到问题问题，提示apt-get install curl 提示没有这个软件源 
解决办法：

sudo add-apt-repository ppa:costamagnagianfranco/ettercap-stable-backports

sudo apt-get update

sudo apt-get install curl

）
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-xenial-prod xenial main" > /etc/apt/sources.list.d/dotnetdev.list'

Ubuntu 14.04

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-trusty-prod trusty main" > /etc/apt/sources.list.d/dotnetdev.list'

Then, update the package cache and install .NET Core

sudo apt-get update
sudo apt-get install dotnet-sdk-2.1.4

RHEL and Fedora based systems

Register the Microsoft key, the product repository for your distro and install required system dependencies with the following scripts.

Fedora, CentOS, Oracle Linux

sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc
sudo sh -c 'echo -e "[packages-microsoft-com-prod]\nname=packages-microsoft-com-prod\nbaseurl=https://packages.microsoft.com/yumrepos/microsoft-rhel7.3-prod\nenabled=1\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc" > /etc/yum.repos.d/dotnetdev.repo'

SUSE Enterprise Linux, OpenSUSE

sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc
sudo sh -c 'echo -e "[packages-microsoft-com-prod]\nname=packages-microsoft-com-prod\nbaseurl=https://packages.microsoft.com/yumrepos/microsoft-rhel7.3-prod\nenabled=1\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc" > /etc/zypp/repos.d/dotnetdev.repo'

Then, update the package cache and install .NET Core

Fedora, CentOS and Oracle Linux

sudo yum update
sudo yum install dotnet-sdk-2.1.4

SUSE Enterprise Linux and OpenSUSE

sudo zypper update
sudo zypper install dotnet-sdk-2.1.4

Note: When installing the SDK, SUSE and OpenSUSE may report that nothing provides libcurl. libcurl should already be installed on supported versions of both distros. Run zypper search libcurl to confirm. The error will present 2 "solutions". Choose "Solution 2" to continue installing .NET Core.

Installation from a binary archive

Installing from the packages detailed above is recommended and you can also install from binary archive. When using binary archives to install, the contents must be extracted to a user location such as $HOME/dotnet and a symbolic link created for dotnet.

mkdir -p $HOME/dotnet && tar zxf dotnet.tar.gz -C $HOME/dotnet
export PATH=$PATH:$HOME/dotnet

Server Hosting

If you are looking to host stand-alone apps on Windows Servers, the ASP.NET Core Module for IIS can be installed separately on servers without installing .NET Core runtime.

Windows

You can download the Windows (Server Hosting) installer and run the following command from an Administrator command prompt: DotNetCore.2.0.5-WindowsHosting.exe

Linux

On supported Linux systems, register the Microsoft Product feed as described above and install dotnet-hosting-2.0.5 using your package manager.

ASP.NET Runtime Core Package Store

The Runtime Package Store is installed by the .NET Core SDK and the Windows Server Hosting installer. If you need to install the Runtime Package Store separately, the following can be used.

• AspNetCore.2.0.5.RuntimePackageStore_x64.exe
• AspNetCore.2.0.5.RuntimePackageStore_x86.exe
