we have a vmss managed by terraform and it install 3 extensions:
AADSSHLoginForLinux
CustomScript
ApplicationHealthLinux
on provisioning of VMs AADSSHLoginForLinux fails with below error, this only started since Friday.
Multiple VM extensions failed to be provisioned on the VM. Please see the VM extension instance view for other failures. The first extension failed due to the error: VM 'xxxx_4' has not reported status for VM agent or extensions. Verify that the OS is up and healthy, the VM has a running VM agent, and that it can establish outbound connections to Azure storage. Please refer to https://aka.ms/vmextensionlinuxtroubleshoot for additional VM agent troubleshooting information.
The failure is caused by the fact that the installation starts at the time when HTTP stack is not quite ready. This is happening only on VMSS, not regular VMs. The VMSS and waagent teams are actively looking for the root cause and a possible fix. As a workaround, change the extension order if you have multiple extensions, or insert a script extension that just waits for a couple of seconds.
Storage access - this is not coming from the extension; probably from the agent. It seems the same HTTP problem.
There is no point to install older extension version because the problem is not in the extension itself but rather the time it is installed.
AADSSHLoginForLinux version: 1.0.2385.1
OS: Ubuntu 20.04LTS
