News, Tutorials, Howtos for Ubuntu Linux
This tutorial shows how to install Microsoft .NET software development framework (9.0, 8.0, or even 6.0, 7.0) in current Ubuntu 24.04, Ubuntu 22.04, and Ubuntu 20.04 LTS.
Microsoft announced .NET 9 last week. It features over 1,000 performance related changes across the runtime, workloads, and languages. .NET Aspire 9 now has OpenAI, Ollama, Milvus integration, and preview support for Azure Functions. For other features and changes, see the announcement.
Wine, the free open-source software for running Windows apps on Linux, macOS, & BSD, announced a new development 9.3 release this Friday.
The new Wine 9.3 improved proxy configuration reading and writing by using new option to query global proxy settings, and wininet functions to set proxy settings.
The release also introduced a new HID pointer device driver, but only matches with digitizer devices for now, it could later be used for HID mice but for now wine use a different path for that.
Other changes in the release include timezone database update, more exception fixes on ARM platforms, and a total of 23 bug-fixes for apps and games, including Free Download Manager, Final Fantasy XI, Solidworks 2008, Virtual Life 2, Microsoft Flight Simulator 2020, and more. For more, see the official release note.
For .NET developers, the latest .NET 8 can be installed on old Ubuntu 18.04 and/or Ubuntu 16.04 LTS easily through PPA.
.NET 8 was released few months ago in November, 2023. It’s a new LTS release with 3 years support, and features new code generator “Dynamic Profile-Guided Optimization” (PGO), AVX-512 instruction set, out-of-the-box AI features, first preview of .NET Aspire, native AoT, and various other changes. See the release note for details.
.NET 8 is made into Ubuntu system repositories for Ubuntu 23.10 and upcoming Ubuntu 24.04. For Ubuntu 22.04 and Ubuntu 20.04 LTS, I’ve written how to install .NET 8 from Microsoft repository.
For users of Ubuntu 16.04 and Ubuntu 18.04 who can’t upgrade the system, there’s now a third-party PPA contains the .NET 8 packages for 64-bit Intel/AMD machines.
The PPA is maintained by Rob Savoury, who maintains so many PPAs with Blender, Chromium, FFmpeg, Firefox, LibreOffice, Qt5/6, Python, LLVM, Node.js, and other popular software packages with old Ubuntu 16.04 and Ubuntu 18.04 support!
UPDATE May 2024: .NET 8 is finally made into Ubuntu 22.04 main repository!! Just open terminal (Ctrl+Alt+T) and run 2 commands one by one to install:
sudo apt update
sudo apt install dotnet8
Microsoft announced .NET 8 a few days ago. Here’s a step by step guide shows how to install it in Ubuntu 22.04 LTS (Also works in Ubuntu 20.04).
.NET 8 is a new LTS release with 3 years support. It features new code generator “Dynamic Profile-Guided Optimization” (PGO), AVX-512 instruction set, out-of-the-box AI features, first preview of .NET Aspire, native AoT, and various other changes. See the release note for details.
And, here are 2 ways to install the .NET 8 in current Ubuntu 22.04 LTS. They are Microsoft’s official repository and Ubuntu PPA.
Ubuntu has included the new release package into system repository for Ubuntu 23.10 and next Ubuntu 24.04.
Don’t know if it will be backported to Ubuntu 22.04 LTS repository, but here you can install it through Microsoft’s official apt repository. And, the repository also supports Ubuntu 20.04!
1. install the key
To add the Microsoft repository, you have to first download & install the key file.
To do so, press Ctrl+Alt+T on keyboard to open terminal. When terminal opens, run single command:
sudo wget -O - https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor | sudo tee /etc/apt/keyrings/microsoft.gpg
This command will download the key, dearmor it (so it’s unreadable code, see the screenshot), and save to ‘/etc/apt/keyrings’ directory.
2. Add the Microsoft repository
Next, in terminal window, run command to create & edit the sources file:
sudo gedit /etc/apt/sources.list.d/microsoft.sources
Depends on your desktop environment, replace gedit with mousepad for XFCE, pluma for MATE, or nano that works in most cases.
When the file opens, add following lines and save it.
Types: deb URIs: https://packages.microsoft.com/ubuntu/22.04/prod/ Suites: jammy Components: main Architectures: amd64 Signed-By: /etc/apt/keyrings/microsoft.gpg
For Ubuntu 20.04, replace 22.04 with 20.04, and jammy with focal.
3. Install .NET 8
Finally, update system package cache by running command:
sudo apt update
And, install .NET 8 SDK, runtime:
sudo apt install dotnet-sdk-8.0
I’m not .NET developer, but you can try dotnet --version after installation to verify.
For choice, .NET 8 is also available to install through an Ubuntu PPA. It so far supports Ubuntu 22.04 on amd64 (Intel/AMD) and arm64 (e.g., Raspberry Pi) devices.
This is a third-party PPA, but maintained by the same people who maintain the .NET8 package in Ubuntu’s system repository for 23.10 & 24.04.
1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to add the PPA:
sudo add-apt-repository ppa:dotnet/dotnet8
2. Linux Mint 21 users need to manually refresh the package cache after adding PPA, by running command:
sudo apt update
3. Finally, just run command to install .net8:
sudo apt install dotnet8
The command will install the host, sdk, runtime, as well as other packages automatically as dependencies.
To remove .NET 8, open terminal (Ctrl+Alt+T) and run command:
sudo apt remove --autoremove aspnetcore-runtime-8.0 dotnet-sdk-8.0 dotnet-runtime-8.0 dotnet8
And, remove the Microsoft repository by running the 2 commands below to delete sources and key files:
sudo rm /etc/apt/keyrings/microsoft.gpg
sudo rm /etc/apt/sources.list.d/microsoft.sources
Finally, run sudo apt update to refresh cache.
If you installed the package from Ubuntu PPA, also run the apt remove command above to uninstall. Then, use the command below to remove the PPA:
sudo add-apt-repository --remove ppa:dotnet/dotnet8
