Exercise 0: Git Security Change Causes Error on VM Creation #13

Closed feaselkl closed 1 week ago

feaselkl commented 4 months ago

Learners receive an error like "post-checkout hook found during git clone disallowed by default" around CreateWinServerVM when trying to create the Hyper-V VM.

The root cause is a Git security change that recently happened: https://github.com/git-lfs/git-lfs/issues/5749

The VM still gets created but create-vm.ps1 doesn't finish successfully and thus doesn't create the on-prem VM within Hyper-V.

The fix is to manually connect to the Azure VM and run the create-vm.ps1 script. It appears that the VM disk zip file does get downloaded to the repo before the script fails, so all of the assets should be in the C:\git folder.

My recommendation would be to add a note to Exercise 0 indicating that if there is an error in that step, to perform the manual fix. A new version of git lfs may obviate this issue, but in the meantime, deliveries of this training may still run into this problem.

This appears to be no longer an issue. The security change was reverted and later corrected, so it will not cause problems for future deliveries.
