説明

act-quality-productivity-squad Auto-Assign Azure CLI Team customer-reported Network question

Describe the bug

On a GitHub-hosted Ubuntu 24.04 runner, az network vnet create intermittently fails because Python detects a module-lock deadlock while importing requests.structures. The failure occurs with Azure CLI 2.89.1 and its bundled Python 3.14.6. It makes our AKS CI workflow flaky: rerunning the same workflow may succeed.

Related command

az network vnet create \
  --resource-group aks-1 \
  --location westus \
  --name aks-vnet \
  --address-prefixes 192.168.8.0/22 fd00::/48

Errors

ERROR: The command failed with an unexpected error. Here is the traceback:
