WSL Install Failures - 2.7.8.0

For those deploying new MCC servers, you may run into an error installing the distro for WSL, this appears to be due to a bug in WSL 2.7.8.0. Affecting KVM & AMD CPU devices.  WSL 2.7.9 should be available shortly to mitigate this issue.

Errors seen:

  • Error code: Wsl/InstallDistro/Service/RegisterDistro/CreateVm/0x800705b4
  • Error code: Wsl/InstallDistro/0x80072eff
  • Failure, expected Distro: Ubuntu-24.04. No Distros found.

The same errors will be seen when running 'wsl --install' which defaults to downloading Ubuntu.

    Hi marty5, this looks consistent with a WSL version-specific install issue rather than an MCC configuration issue. I would hold deployment on affected KVM and AMD systems until WSL 2.7.9 or later is available, then retest the Ubuntu distro install before rolling forward. For production builds, pinning or validating the WSL version before MCC deployment would save a lot of rebuild time.
