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:<\/b><\/p>\n

sudo apt update<\/pre>\n
sudo apt install dotnet8<\/pre>\n
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).<\/p>\n
.NET 8 is a new LTS release with 3 years support. It features new code generator \u201cDynamic Profile-Guided Optimization\u201d (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<\/a> for details.<\/p>\n
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.<\/p>\n
Option 1: Install .NET 8 SDK\/Run-time via official repository<\/h3>\n
Ubuntu has included the new release package into system repository for Ubuntu 23.10 and next Ubuntu 24.04.<\/p>\n
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!<\/p>\n
1. install the key<\/b><\/p>\n
To add the Microsoft repository, you have to first download & install the key file.<\/p>\n
To do so, press Ctrl+Alt+T<\/b> on keyboard to open terminal. When terminal opens, run single command:<\/p>\n
sudo wget -O - https:\/\/packages.microsoft.com\/keys\/microsoft.asc | gpg --dearmor | sudo tee \/etc\/apt\/keyrings\/microsoft.gpg<\/pre>\n
This command will download the key, dearmor it (so it’s unreadable code, see the screenshot), and save to ‘\/etc\/apt\/keyrings’ directory.<\/i><\/p>\n
\"\"<\/a><\/p>\n
2. Add the Microsoft repository<\/b><\/p>\n
Next, in terminal window, run command to create & edit the sources file:<\/p>\n
sudo gedit \/etc\/apt\/sources.list.d\/microsoft.sources<\/pre>\n
Depends on your desktop environment, replace gedit<\/code> with mousepad<\/code> for XFCE, pluma<\/code> for MATE, or nano<\/code> that works in most cases.<\/i><\/p>\n
When the file opens, add following lines and save it.<\/p>\n
Types: deb\r\nURIs: https:\/\/packages.microsoft.com\/ubuntu\/22.04<\/b>\/prod\/\r\nSuites: jammy<\/b>\r\nComponents: main\r\nArchitectures: amd64\r\nSigned-By: \/etc\/apt\/keyrings\/microsoft.gpg<\/pre>\n
For Ubuntu 20.04, replace 22.04<\/code> with 20.04<\/code>, and jammy<\/code> with focal<\/code><\/i>.<\/p>\n
\"\"<\/a><\/p>\n
3. Install .NET 8<\/b><\/p>\n
Finally, update system package cache by running command:<\/p>\n
sudo apt update<\/pre>\n
And, install .NET 8 SDK, runtime:<\/p>\n
sudo apt install dotnet-sdk-8.0<\/pre>\n
I’m not .NET developer, but you can try dotnet --version<\/code> after installation to verify.<\/p>\n
\"\"<\/a><\/p>\n
Option 2: Install .NET 8 from Ubuntu PPA<\/h3>\n
For choice, .NET 8 is also available to install through an Ubuntu PPA<\/a>. It so far supports Ubuntu 22.04 on amd64 (Intel\/AMD) and arm64 (e.g., Raspberry Pi) devices.<\/p>\n
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.<\/b><\/p>\n
1. First, press Ctrl+Alt+T<\/code> on keyboard to open terminal. When it opens, run command to add the PPA:<\/p>\n
sudo add-apt-repository ppa:dotnet\/dotnet8<\/pre>\n
\"\"<\/a>
\n2. Linux Mint 21 users need to manually refresh the package cache after adding PPA, by running command:<\/p>\n
sudo apt update<\/pre>\n
3. Finally, just run command to install .net8:<\/p>\n
sudo apt install dotnet8<\/pre>\n
The command will install the host, sdk, runtime, as well as other packages automatically as dependencies.<\/p>\n
\"\"<\/a><\/p>\n
Uninstall .NET 8<\/h3>\n
To remove .NET 8, open terminal (Ctrl+Alt+T) and run command:<\/p>\n
sudo apt remove --autoremove aspnetcore-runtime-8.0 dotnet-sdk-8.0 dotnet-runtime-8.0 dotnet8<\/pre>\n
And, remove the Microsoft repository by running the 2 commands below to delete sources and key files:<\/p>\n
sudo rm \/etc\/apt\/keyrings\/microsoft.gpg<\/pre>\n
sudo rm \/etc\/apt\/sources.list.d\/microsoft.sources<\/pre>\n
Finally, run sudo apt update<\/code> to refresh cache.<\/p>\n
If you installed the package from Ubuntu PPA, also run the apt remove<\/code> command above to uninstall. Then, use the command below to remove the PPA:<\/p>\n
sudo add-apt-repository --remove ppa:dotnet\/dotnet8<\/pre>","protected":false},"excerpt":{"rendered":"
