Install .NET Runtime with Snap

  • Artikkeli

This article describes how to install the .NET Runtime snap package. .NET Runtime snap packages are provided by and maintained by Canonical. Snaps are a great alternative to the package manager built into your Linux distribution.

A snap is a bundle of an app and its dependencies that works across many different Linux distributions. Snaps are discoverable and installable from the Snap Store. For more information about Snap, see Quickstart tour.

Caution

Snap installations of .NET may have problems running .NET tools. If you wish to use .NET tools, we recommend that you install .NET using the dotnet-install script or the package manager for the particular Linux distribution.

Prerequisites

  • Linux distribution that supports snap.
  • snapd the snap daemon.

Your Linux distribution might already include snap. Try running snap from a terminal to see if the command works. For a list of supported Linux distributions, and instructions on how to install snap, see Installing snapd.

.NET releases

Microsoft publishes .NET under two different support policies, Long Term Support (LTS) and Standard Term Support (STS). The quality of all releases is the same. The only difference is the length of support. LTS releases get free support and patches for three years. STS releases get free support and patches for 18 months. For more information, see .NET Support Policy.

The versions of .NET that are currently supported by Microsoft are:

  • 8.0 (LTS)—Support ends November 10, 2026.
  • 6.0 (LTS)—Support ends November 12, 2024.

Other entities that build and release .NET might introduce different support policies. Be sure to check with them to understand how .NET is supported.

1. Install the runtime

The following steps install the .NET 8 runtime snap package:

  1. Open a terminal.

  2. Use snap install to install the .NET Runtime snap package. For example, the following command installs the .NET 8 runtime.

    sudo snap install dotnet-runtime-80

Each .NET Runtime is published as an individual snap package. The following table lists the packages:

.NET version Snap package .NET version supported by Microsoft
8 (STS) dotnet-runtime-80 Yes
7 (STS) dotnet-runtime-70 No
6 (LTS) dotnet-runtime-60 Yes
5 dotnet-runtime-50 No
3.1 dotnet-runtime-31 No
3.0 dotnet-runtime-30 No
2.2 dotnet-runtime-22 No
2.1 dotnet-runtime-21 No

2. Enable the dotnet command

When the .NET runtime snap package is installed, the dotnet command isn't automatically configured. Use the snap alias command to use the dotnet command from the terminal. The command is formatted as: sudo snap alias {package}.{command} {alias}. The following example maps the dotnet command:

sudo snap alias dotnet-runtime-80.dotnet dotnet

3. Export the install location

The DOTNET_ROOT environment variable is often used by tools to determine where .NET is installed. When .NET is installed through Snap, this environment variable isn't configured. You should configure the DOTNET_ROOT environment variable in your profile. The path to the snap uses the following format: /snap/{package}/current. For example, if you installed the dotnet-runtime-80 snap, use the following command to set the environment variable to where .NET is located:

export DOTNET_ROOT=/snap/dotnet-runtime-80/current

Export the environment variable permanently

The preceding export command only sets the environment variable 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 export DOTNET_ROOT=/snap/dotnet-runtime-80/current.

Troubleshooting

The dotnet terminal command doesn't work

Snap packages can map an alias to a command provided by the package. The .NET Runtime snap packages don't automatically lias the dotnet command. To alias the dotnet command to the snap package, use the following command:

sudo snap alias dotnet-runtime-80.dotnet dotnet

Substitute dotnet-runtime-80 with the name of your runtime package.

Can't install Snap on WSL2

systemd must be enabled on the WSL2 instance before Snap can be installed.

  1. Open /etc/wsl.conf in a text editor of your choice.

  2. Paste in the following configuration:

    [boot]
systemd=true

  3. Save the file and restart the WSL2 instance through PowerShell. Use the wsl.exe --shutdown command.

4. Use the .NET CLI

Open a terminal and type dotnet.

dotnet

You'll see output similar to the following:

Usage: dotnet [options]
Usage: dotnet [path-to-application]

Options:
  -h|--help         Display help.
  --info            Display .NET information.
  --list-sdks       Display the installed SDKs.
  --list-runtimes   Display the installed runtimes.

path-to-application:
  The path to an application .dll file to execute.
