Can’t Install .NET 10 on Ubuntu via apt? Here’s a Workaround That Actually Works
I recently tried installing .NET 10 SDK on Ubuntu 24.04 (Noble) using apt, following Microsoft’s documentation. It should have been simple. But, I ran into this: If you’re seeing the same error — this post is for you. dotnet-sdk-10.0 may not be available via apt yet, depending on your region This is due to APT repository propagation, not a broken setup Microsoft’s official install script is the supported workaround Installing the SDK also installs the runtime You can safely keep .NET 8, 9, and 10 side-by-side The Problem: apt Can’t Find .NET 10 (Yet) I already had Microsoft’s Ubuntu repo configured: https://packages.microsoft.com/ubuntu/24.04/prod Still, installing the SDK failed: Microsoft rolls out APT packages gradually across mirrors and regions. That means: Some users can install .NET 10 immediately Others won’t see it yet apt cannot install packages that haven’t reached your mirror You can confirm availability with: If it says “Unable to locate package”, the SDK simply isn’t there yet. The Workaround: Microsoft's Official Install Script Until the APT package reaches your region, the recommended workaround is Microsoft’s own installer script. ✅** Install .NET 10 SDK** This installs .NET 10 under: ⚠️Important: Set Environment Variables If you install via the script, you must add .NET to your PATH. Add this to your shell profile (~/.bashrc or ~/.zshrc): Then reload your shell: Side-by-Side with .NET 8 and 9 Installing .NET 10 this way does not break existing installations. Once dotnet-sdk-10.0 becomes available via apt in your region, you can switch back to a fully package-managed setup. If apt can’t find .NET 10 on Ubuntu 24.04 yet: You’re not misconfigured The package just hasn’t reached your mirror The official install script is safe and supported I’ll still switch back to installing .NET 10 via apt once it’s available in my region — but until then, this workaround works perfectly.
