\"Mascote<\/p>\n

Anyone still saying \u201c.NET Core 10\u201d has the history right \u2014 the Core name ended at 3.1. Since 5, the platform has been called simply .NET<\/strong>. 10 came out on November 11, 2025, is LTS until November 14, 2028, and in September 2026, the stable SDK is 10.0.400<\/strong> (runtime 10.0.11, C# 14). Below: Ubuntu, Debian, Fedora\/RHEL, the official script, and a tarball \u2014 just one path, without mixing feeds.<\/p>\n

<\/p>\n

SDK or just the runtime<\/h2>\n

For development, install the SDK<\/strong> (dotnet-sdk-10.0<\/code>). It already includes the runtime and ASP.NET Core. To only run a published app without a bundled runtime, the most useful package is aspnetcore-runtime-10.0<\/code>. Check what is already on the machine:<\/p>\n

dotnet --info\ndotnet --list-sdks\ndotnet --list-runtimes\n<\/code><\/pre>\n
Ubuntu (the distribution\u2019s route)<\/h2>\n
Microsoft no longer publishes<\/strong> .NET packages in its feed for Ubuntu 22.04 onward. Use Canonical\u2019s APT \u2014 and a single feed. On 24.04 LTS, 25.04, 25.10, and 26.04, 10 is already in the native repository:<\/p>\n
sudo apt-get update\nsudo apt-get install -y dotnet-sdk-10.0\ndotnet --version\n<\/code><\/pre>\n
On Ubuntu 22.04<\/strong> the native APT stops at 8. 10 comes from Canonical\u2019s backports PPA:<\/p>\n
sudo add-apt-repository ppa:dotnet\/backports\nsudo apt-get update\nsudo apt-get install -y dotnet-sdk-10.0\n<\/code><\/pre>\n
Do not add packages.microsoft.com<\/code> \u201cjust in case.\u201d Mixing Microsoft\u2019s feed with the distribution\u2019s is the classic cause of libhostfxr.so<\/code> \/ SDK not found. Choose one.<\/p>\n
Debian 12 and 13<\/h2>\n
Here, Microsoft\u2019s feed still applies. Debian 13:<\/p>\n
wget https:\/\/packages.microsoft.com\/config\/debian\/13\/packages-microsoft-prod.deb -O packages-microsoft-prod.deb\nsudo dpkg -i packages-microsoft-prod.deb\nrm packages-microsoft-prod.deb\nsudo apt-get update\nsudo apt-get install -y dotnet-sdk-10.0\n<\/code><\/pre>\n
On Debian 12, change the path to config\/debian\/12\/packages-microsoft-prod.deb<\/code>. The 10 feed publishes x64 and Arm64; Arm32 requires the script or tarball.<\/p>\n
Fedora, RHEL, and CentOS Stream<\/h2>\n
Native package, no extra repository. Fedora 43\/44, RHEL 8\/9\/10 (AppStream, registered subscription), and CentOS Stream 9\/10:<\/p>\n
sudo dnf install dotnet-sdk-10.0\n<\/code><\/pre>\n
On the server, if the app does not include the runtime when published: sudo dnf install aspnetcore-runtime-10.0<\/code>.<\/p>\n
Official script or tarball (any distribution)<\/h2>\n
No root, no messing with APT. The script installs the current LTS \u2014 today, 10 \u2014 in ~\/.dotnet<\/code>:<\/p>\n
curl -L https:\/\/dot.net\/v1\/dotnet-install.sh -o dotnet-install.sh\nchmod +x dotnet-install.sh\n.\/dotnet-install.sh --channel 10.0\necho 'export DOTNET_ROOT=$HOME\/.dotnet' >> ~\/.profile\necho 'export PATH=$PATH:$HOME\/.dotnet:$HOME\/.dotnet\/tools' >> ~\/.profile\nsource ~\/.profile\ndotnet --version\n<\/code><\/pre>\n
The SDK 10.0.400 tarball (same contents, you choose the folder):<\/p>\n
case $(uname -m) in\n  x86_64)  ARCH=x64 ;;\n  aarch64) ARCH=arm64 ;;\n  *) echo \"arch n\u00e3o suportada\"; exit 1 ;;\nesac\nVER=10.0.400\ncd \/tmp\ncurl -fLO \"https:\/\/builds.dotnet.microsoft.com\/dotnet\/Sdk\/${VER}\/dotnet-sdk-${VER}-linux-${ARCH}.tar.gz\"\nmkdir -p \"$HOME\/.dotnet\"\ntar -C \"$HOME\/.dotnet\" -xzf \"\/tmp\/dotnet-sdk-${VER}-linux-${ARCH}.tar.gz\"\n<\/code><\/pre>\n
The same PATH as with the script. Each file\u2019s SHA-256 checksum is on the 10.0 download page<\/a>.<\/p>\n
Snap (if the distribution only has snap)<\/h2>\n
Canonical packages dotnet-sdk-100<\/code>. It works, but Microsoft itself warns: dotnet tool<\/code> and dotnet watch<\/code> often break with snap. Prefer APT, dnf, or the script for development.<\/p>\n
sudo snap install dotnet-sdk-100\nsudo ln -s \/snap\/dotnet-sdk-100\/current\/usr\/bin\/dotnet \/usr\/local\/bin\/dotnet\nexport DOTNET_ROOT=\/snap\/dotnet-sdk-100\/current\/usr\/lib\/dotnet\n<\/code><\/pre>\n
Do not mix snap and APT in the same PATH<\/code>.<\/p>\n
Hello, net10.0<\/h2>\n
With the SDK in PATH<\/code>:<\/p>\n
dotnet new console -n OlaLinux -o ola --framework net10.0\ncd ola\ndotnet run\n<\/code><\/pre>\n
The template already generates a .csproj<\/code> with TargetFramework<\/code> net10.0<\/code>. Web: dotnet new webapi -n ApiLinux<\/code>. Starting with 10, dotnet new sln<\/code> creates the SLNX format \u2014 it is the new default, not an error.<\/p>\n
Wrap-up<\/h2>\n
One package (dotnet-sdk-10.0<\/code>) or one script in ~\/.dotnet<\/code>. Just one feed. One dotnet new<\/code>. Core in the name is nostalgia; the platform on Linux, in 2026, is .NET 10 LTS.<\/p>\n
Language map: The 7 main programming languages<\/a>. Toolchain siblings: Go<\/a>, Swift<\/a>, Python<\/a>.<\/p>\n
