** Description changed:
This is the tracking bug for the .NET 8 November 2025 release.
[Impact]
* This corresponds to an upstream microrelease released on November 11th,
2025. See also:
- .NET blog entry:
https://devblogs.microsoft.com/dotnet/dotnet-and-dotnet-framework-november-2025-servicing-updates/
- release announcement:
https://github.com/dotnet/source-build/discussions/5414
- .NET 8.0.22 Runtime release notes:
https://github.com/dotnet/core/blob/main/release-notes/8.0/8.0.22/8.0.22.md
- .NET 8.0.122 SDK release notes:
https://github.com/dotnet/core/blob/main/release-notes/8.0/8.0.22/8.0.122.md
* It is beneficial for all our users (including LTS users) to have
access to the latest .NET stack.
[Test Case]
* The package should build successfully in -proposed (respectively).
* The packages should be installable on jammy, noble, plucky, questing on
amd64, arm64, s390x and ppc64el architectures.
* Autopackage tests should pass.
[Regression Potential]
* The dotnet8 package has no reverse dependencies.
* The upstream testing routine is usually satisfactory (see for example
Microsoft's public Azure Pipeline for .NET related repositories:
https://dev.azure.com/dnceng-public/public/_build), but there is always
a risk of something breaking.
[Other]
* The tarball originated from here: https://github.com/canonical/dotnet-
source-build-security/actions/runs/19172995729
* 8.0.22 is the version number of the .NET Runtime and 8.0.122 is the version
number of the .NET SDK.
* We are only building the 8.0.1xx feature band, because this is the only
feature band that allows building from source. See explanation of feature
bands:
https://learn.microsoft.com/en-us/dotnet/core/releases-and-support#feature-bands-sdk-only
* Overview of how dotnet is versioned: https://learn.microsoft.com/en-
us/dotnet/core/versions/
* PPA for review: https://launchpad.net/~mateus-
morais/+archive/ubuntu/dotnet-november-2025-updates
* .NET 8 on questing FTBFS on the amd64v3 architecture variant. This is
expected and not a regression.
+
+ * Per the .NET toolchain's policy, .NET 8 will not be included in
+ resolute, therefore, there won't be a resolute build uploaded. There is
+ currently a removal bug filed for dotnet8 on resolute:
