Installation of the Azure Trusted Signing Tools is freezing the runner and workaround with setup-dotnet is causing the signtool to fail #156
Description
Type of issue
- Error when running a workflow.
- Request for additional tools or software for an existing image.
- Request for a new image, Linux or Windows.
- Other
Describe the issue
Installation of the Azure Trusted Signing Tools is freezing the latest runner.
To Reproduce
As described in the original issue related to official runners the problem started to occur with the latest runners and installation of Trusted Signing either from winget or manual is causing the runner to freeze (probably waiting for some user interaction there on the latest runner).
The installer of Trusted Signing has not changed for a long time, so it's definetely related to some latest runner changes.
We found that using actions/setup-dotnet is fixing the problem for original machines, but for ARM64 even though it is helping out with the installation, later in the process it's causing the signtool to fail with exit code 3.
Expected behavior
I would expect to be able to use Trusted Signing on all machines as before (everything was fine on 13.01.2026)
Desktop (please complete the following information):
- OS: Windows 11 ARM64
Additional context
Similar problem is happening on the official runners, but the setup-dotnet workaround is allowing us to continue, meanwhile arm64 is still causing problems and not solvable at the moment.
