Rebecca,

I agree there is value in running tests against latest versions of all components and there is value in using stable releases of all dependent components.

There is overhead to do both.  There is also overhead to monitor all dependent components, evaluate new releases, and update versions of dependent components.  I do not know how to automate these types of evaluations.

Thanks,

Mike

Hi Mike,



That does appear to be the current general approach, but I'd suggest changing it.

Because in the last week before release we shouldn't be chasing new versions of unrelated software, in my opinion.



Fortunately the switch to Ubuntu 20.04 hasn't happened yet, and is due to be rolled out beginning November 30th (https://github.com/actions/virtual-environments/issues/1816). The CI pipeline has a set of warnings: "##[warning]Ubuntu-latest pipelines will use Ubuntu-20.04 soon. For more details, see https://github.com/actions/virtual-environments/issues/1816"

Hi Rebecca,



I think the general approach is to verify the latest version of everything

including the CI infrastructure components.



If a failure is detected due to a new component, then we can temporarily

lock in a previous stable version until the issues with the new component

are resolved.

Related, should we use a known version of Ubuntu in testing?



Currently, there are several lines with 'ubuntu-latest' - e.g.:



.azurepipelines/Ubuntu-GCC5.yml:17:    vm_image: 'ubuntu-latest'

.azurepipelines/Ubuntu-PatchCheck.yml:21:  vmImage: 'ubuntu-latest'



OvmfPkg/PlatformCI/.azurepipelines/Ubuntu-GCC5.yml:20: vm_image:

'ubuntu-latest'





I'm not familiar with how Azure works, but could this cause problems

when they update their Ubuntu latest image to 21.04 etc. and things

change under us?

The QEMU release from 2020.11.20 is installed into the incorrect

directory and is causing EDK II CI failures in the run to shell

step.
