Installer freezes in windows-2022 GitHub Action

[Michele Locati]

Hello everybody,

In a GitHub Action running on windows-2022 [1], I have a couple of
steps like this:

-
  name: Download Cygwin installer
  shell: pwsh
  run: |
    Invoke-WebRequest -Uri https://cygwin.com/setup-x86_64.exe
-OutFile C:\CygwinInstaller.exe
    $expectedHash = (Invoke-WebRequest -Uri
https://cygwin.com/sha512.sum).ToString()
    $actualHash = Get-FileHash -LiteralPath C:\CygwinInstaller.exe
-Algorithm SHA512
    if (-not($expectedHash.ToLower().Contains("${$actualHash.Hash.ToLower()}
 setup-x86_64.exe"))) {
      throw 'Invalid hash of downloaded cygwin installer'
    }
-
  name: Install Cygwin
  shell: cmd
  run: >
    C:\CygwinInstaller.exe
    --root C:\cygwin
    --local-package-dir C:\cygwin-packages
    --packages wget,file,make,unzip,dos2unix,mingw64-x86_64-gcc-core,mingw64-x86_64-gcc-g++,mingw64-x86_64-headers,mingw64-x86_64-runtime
    --site https://mirrors.kernel.org/sourceware/cygwin/
    --only-site
    --quiet-mode
    --upgrade-also
    --no-shortcuts
    --no-admin
    --no-replaceonreboot
    --no-version-check
    --no-write-registry
    --verbose

The problem is that sometimes (but not always) the second step gets
stuck: absolutely nothing is printed (even if the --verbose option is
specified) and GitHub aborts the execution after a few hours.

Has anyone encountered this problem before? What could be the cause?
Is there a solution?
