.NET is supported on Ubuntu. This article describes how to install .NET on Ubuntu. When an Ubuntu version falls out of support, .NET is no longer supported with that version. However, these instructions may help you to get .NET running on those versions, even though it isn't supported.

Install the SDK (which includes the runtime) if you want to develop .NET apps. Or, if you only need to run apps, install the Runtime. If you're installing the Runtime, we suggest you install the ASP.NET Core Runtime as it includes both .NET and ASP.NET Core runtimes.

If you've already installed the SDK or Runtime, use the dotnet --list-sdks and dotnet --list-runtimes commands to see which versions are installed. For more information, see How to check that .NET is already installed.

For consumers, coders, and enterprises, Ubuntu Linux 18.04 is a free, customizable, and highly usable alternative to both macOS and Windows. However, getting started with Ubuntu is more. 18.04 + 6 months = 18.10. Yep, that's right. And that's why it is 18.10 and not 18.1. That trailing zero has meaning. All Ubuntu versions end with.04 (April release) or.10 (October release). There is always 6 months between them (unless they decide to change it later). And the interim life cycles are 9 months long. In reviewing Ubuntu 18.04 LTS, Michael Larabel of Phoronix wrote, 'Ubuntu 18.04 is mostly an incremental upgrade over Ubuntu 17.10 with updated packages, the switch back to X.Org session by default rather than Wayland, continued presence of Snaps, and a variety of minor user-interface updates. It's really not a big deal going from 17.10 to 18.

Important

Package manager installs are only supported on the x64 architecture. Other architectures, such as ARM, must manually install .NET. For more information, see the manual install section.

Supported distributions

The following table is a list of currently supported .NET releases and the versions of Ubuntu they're supported on. These versions remain supported until either the version of .NET reaches end-of-support or the version of Ubuntu reaches end-of-life.

• A ✔️ indicates that the version of Ubuntu or .NET is still supported.
• A ❌ indicates that the version of Ubuntu or .NET isn't supported on that Ubuntu release.
• When both a version of Ubuntu and a version of .NET have ✔️, that OS and .NET combination is supported.

The following versions of .NET are no longer supported. The downloads for these still remain published:

• 3.0
• 2.2
• 2.0

Remove preview versions

When using a package manager to manage your installation of .NET, you may run into a conflict if you've previously installed a preview release. The package manager may interpret the non-preview release as an earlier version of .NET. To install the non-preview release, first uninstall the preview versions. For more information about uninstalling .NET, see How to remove the .NET Runtime and SDK.

How to install other versions

The packages added to package manager feeds are named in a hackable format: {product}-{type}-{version}.

• product
  The type of .NET product to install. Valid options are:

  • dotnet
  • aspnetcore

• type
  Chooses the SDK or the runtime. Valid options are:

  • sdk
  • runtime

• version
  The version of the SDK or runtime to install. This article will always give the instructions for the latest supported version. Valid options are any released version, such as:

  • 5.0
  • 3.1
  • 3.0
  • 2.1

  It's possible the SDK/runtime you're trying to download is not available for your Linux distribution. For a list of supported distributions, see .NET Core dependencies and requirements.

Examples

• Install the ASP.NET Core 5.0 runtime: aspnetcore-runtime-5.0
• Install the .NET Core 2.1 runtime: dotnet-runtime-2.1
• Install the .NET 5.0 SDK: dotnet-sdk-5.0
• Install the .NET Core 3.1 SDK: dotnet-sdk-3.1

Package missing

If the package-version combination doesn't work, it's not available. For example, there isn't an ASP.NET Core SDK, the SDK components are included with the .NET SDK. The value aspnetcore-sdk-2.2 is incorrect and should be dotnet-sdk-2.2. For a list of Linux distributions supported by .NET Core, see .NET dependencies and requirements.

There are two placeholders in the following set of commands.

• {dotnet-package}
  This represents the .NET package you're installing, such as aspnetcore-runtime-3.1. This is used in the following sudo apt-get install command.

• {os-version}
  This represents the Linux version you are on. This is used in the wget command below.

First, try purging the package list:

Then, try to install .NET again. If that doesn't work, you can run a manual install with the following commands:

Failed to fetch

While installing the .NET package, you may see an error similar to Failed to fetch . File has unexpected size . Mirror sync in progress?. This error could mean that the package feed for .NET is being upgraded with newer package versions, and that you should try again later. During an upgrade, the package feed shouldn't be unavailable for more than 30 minutes. If you continually receive this error for more than 30 minutes, please file an issue at https://github.com/dotnet/core/issues.

Snap

A snap is a bundle of an app and its dependencies that works without modification across many different Linux distributions. Snaps are discoverable and installable from the Snap Store. For more information about Snap, see Getting started with Snap.

Only supported versions of .NET Core are available through Snap.

Install the SDK

Snap packages for .NET SDK are all published under the same identifier: dotnet-sdk. A specific version of the SDK can be installed by specifying the channel. The SDK includes the corresponding runtime. The following table lists the channels:

Use the snap install command to install a .NET SDK snap package. Use the --channel parameter to indicate which version to install. If this parameter is omitted, latest/stable is used. In this example, 5.0 is specified:

Next, register the dotnet command for the system with the snap alias command:

This command is formatted as: sudo snap alias {package}.{command} {alias}. You can choose any {alias} name you would like. For example, you could name the command after the specific version installed by snap: sudo snap alias dotnet-sdk.dotnet dotnet50. When you use the command dotnet50, you'll invoke this specific version of .NET. But this is incompatible with most tutorials and examples as they expect a dotnet command to be available.

Install the runtime

Snap packages for .NET Core Runtime are each published under their own package identifier. The following table lists the package identifiers:

Use the snap install command to install a .NET Runtime snap package. In this example, .NET 5.0 is installed:

Next, register the dotnet command for the system with the snap alias command:

This command is formatted as: sudo snap alias {package}.{command} {alias}. You can choose any {alias} name you would like. For example, you could name the command after the specific version installed by snap: sudo snap alias dotnet-runtime-50.dotnet dotnet50. When you use the command dotnet50, you'll invoke this specific version of .NET. But this is incompatible with most tutorials and examples as they expect a dotnet command to be available.

SSL Certificate errors

When .NET is installed through Snap, it's possible that on some distros the .NET SSL certificates may not be found and you may receive an error similar to the following during restore:

To resolve this issue, set a few environment variables:

The certificate location will vary by distro. Here are the locations for the distros where we have experienced the issue.

• Fedora - /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
• OpenSUSE - /etc/ssl/ca-bundle.pem
• Solus - /etc/ssl/certs/ca-certificates.crt

Dependencies

When you install with a package manager, these libraries are installed for you. But, if you manually install .NET or you publish a self-contained app, you'll need to make sure these libraries are installed:

• libc6
• libgcc1
• libgssapi-krb5-2
• libicu52 (for 14.x)
• libicu55 (for 16.x)
• libicu60 (for 18.x)
• libicu66 (for 20.x)
• libssl1.0.0 (for 14.x, 16.x)
• libssl1.1 (for 18.x, 20.x)
• libstdc++6
• zlib1g

For .NET apps that use the System.Drawing.Common assembly, you also need the following dependency:

• libgdiplus (version 6.0.1 or later)

  Warning

  You can install a recent version of libgdiplus by adding the Mono repository to your system. For more information, see https://www.mono-project.com/download/stable/.

Scripted install

The dotnet-install scripts are used for automation and non-admin installs of the SDK and Runtime. You can download the script from https://dot.net/v1/dotnet-install.sh.

The script defaults to installing the latest SDK long term support (LTS) version, which is .NET Core 3.1. To install the current release, which may not be an (LTS) version, use the -c Current parameter.

To install .NET Runtime instead of the SDK, use the --runtime parameter.

You can install a specific version by altering the -c Format external hard drive. parameter to indicate the specific version. The following command installs .NET SDK 5.0.

For more information, see dotnet-install scripts reference.

Manual install

As an alternative to the package managers, you can download and manually install the SDK and runtime. Manual install is usually performed as part of continuous integration testing or on an unsupported Linux distribution. For a developer or user, it's generally better to use a package manager.

If you install .NET SDK, you don't need to install the corresponding runtime. First, download a binary release for either the SDK or the runtime from one of the following sites:

• ✔️ .NET 5.0 downloads
• ✔️ .NET Core 3.1 downloads
• ✔️ .NET Core 2.1 downloads

Next, extract the downloaded file and use the export command to set variables used by .NET and then ensure .NET is in PATH.

To extract the runtime and make the .NET CLI commands available at the terminal, first download a .NET binary release. Then, open a terminal and run the following commands from the directory where the file was saved. The archive file name may be different depending on what you downloaded.

Use the following command to extract the runtime:

Use the following command to extract the SDK:

Tip

The preceding export commands only make the .NET CLI commands available for the terminal session in which it was run.

You can edit your shell profile to permanently add the commands. There are a number of different shells available for Linux and each has a different profile. For example:

• Bash Shell: ~/.bash_profile, ~/.bashrc
• Korn Shell: ~/.kshrc or .profile
• Z Shell: ~/.zshrc or .zprofile

Edit the appropriate source file for your shell and add :$HOME/dotnet to the end of the existing PATH statement. If no PATH statement is included, add a new line with export PATH=$PATH:$HOME/dotnet.

Also, add export DOTNET_ROOT=$HOME/dotnet to the end of the file.

This approach lets you install different versions into separate locations and choose explicitly which one to use by which application.
