TigerVNC is a free, open-source and high-performance VNC server used to control or access Linux based desktop remotely. It is a client/server application that allows you to interact with graphical applications on remote machines. In this tutorial, we will show you how to install and configure VNC server on Ubuntu 20.04.
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.
Important
Package manager installs are only supported on the x64 architecture. Other architectures, such as ARM, must install .NET by some other means such as with Snap, an installer script, or through a manual binary installation.
For more information on installing .NET without a package manager, see one of the following articles:
Supported distributionsThe 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.

Remove preview versionsWhen 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 versionsThe 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.
ExamplesInstall 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 missingIf 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.
Use APT to update .NETWhen a new patch release is available for .NET, you can simply upgrade it through APT with the following commands:
APT troubleshootingThis section provides information on common errors you may get while using APT to install .NET.
Unable to find packageUbuntu 64 Bit IntelImportant
Package manager installs are only supported on the x64 architecture. Other architectures, such as ARM, must install .NET by some other means such as with Snap, an installer script, or through a manual binary installation.
For more information on installing .NET without a package manager, see one of the following articles:
Unable to locate  Some packages could not be installedIf you receive an error message similar to Unable to locate package {dotnet-package} or Some packages could not be installed, run the following commands.
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 fetchWhile 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.
DependenciesWhen 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/.
